PiecewiseLinear
Linearly interpolates between pairs of x-y data
Description
The PiecewiseLinear function performs linear interpolations between user-provided pairs of x-y data. The x-y data can be provided in three ways. The first way is through a combination of the x and y paramaters, which are lists of the x and y coordinates of the data points that make up the function. The second way is in the xy_data parameter, which is a list of pairs of x-y data that make up the points of the function. This allows for the function data to be specified in columns by inserting line breaks after each x-y data point. Finally, the x-y data can be provided in an external file containing comma-separated values. The file name is provided in data_file, and the data can be provided in either rows (default) or columns, as specified in the format parameter.
By default, the x-data corresponds to time, but this can be changed to correspond to x, y, or z coordinate with the axis line. If the function is queried outside of its range of x data, it returns the y value associated with the closest x data point.

#
# Pressure Test
#
# This test is taken from the Abaqus verification manual:
# "1.3.4 Axisymmetric solid elements"
#
# The two lower nodes are not allowed to translate in the z direction.
# Step 1:
# Pressure of 1000 is applied on each face.
# Step 2:
# Step 1 load plus a pressure on the vertical faces that varies from
# 0 to 1000 from top to bottom.
#
# Solution:
# Step 1:
# Stress xx, yy, zz = -1000
# Stress xy = 0
# Step 2:
# Stress xx, zz = -1500
# Stress yy = -1000
# Stress xy = 0

#
# 1-D Gap Heat Transfer Test without mechanics
#
# This test exercises 1-D gap heat transfer for a helium-filled gap including radiation.
#
# The mesh consists of two element blocks containing one element each. Each
# element is a unit cube. They sit next to one another with a unit between them.
#
# The conductivity of both blocks is set very large to achieve a uniform temperature
# across each block. The temperature of the far left boundary
# is ramped from 100 to 200 over one time unit, and then held fixed for an additional
# time unit. The temperature of the far right boundary is held fixed at 100.
#
# A simple analytical solution is possible for the heat flux between the blocks:
#
# Flux = (T_left - T_right) * h_gap
#
# where h_gap = h_gas + h_cont + h_rad
#
# By setting the contact pressure, roughnesses, and jump distances to zero, the gap
# conductance simplifies to:
#
# h_gap = gapK/d_gap + sigma*Fe*(T_left^2 + T_right^2)*(T_left + T_right)
#
# where Fe = 1/(1/eps_left + 1/eps_right - 1)
# eps = emissivity
#
# For pure helium, BISON computes the gas conductivity as:
#
# gapK(Tavg) = 2.639e-3*Tavg^0.7085
#
# For the test, the final (t=2) average gas temperature is (200 +100)/2 = 150,
# giving gapK(150) = 0.09187557
#
# Assuming ems_left = ems_right = 0.5, Fe = 1/3
#
# The heat flux across the gap at that time is then:
#
# Flux(2) = 100 * ((0.09187557/1.0) + (5.669e-8/3)*(200^2 + 100^2)*(200 + 100))
# = 37.532557
#
# The flux post processors give 37.53255
#

# This tests the thermal expansion coefficient function using both
# options to specify that function: mean and instantaneous. There
# two blocks, each containing a single element, and these use the
# two variants of the function.
# In this test, the instantaneous CTE function has a constant value,
# while the mean CTE function is an analytic function designed to
# give the same response. If \bar{alpha}(T) is the mean CTE function,
# and \alpha(T) is the instantaneous CTE function,
# \bar{\alpha}(T) = 1/(T-Tref) \intA^{T}_{Tsf} \alpha(T) dT
# where Tref is the reference temperature used to define the mean CTE
# function, and Tsf is the stress-free temperature.
# The two models produce very similar results. There are slight
# differences due to the large deformation treatment.

#
# 1x1x1 unit cube with time-varying pressure on top face
#
# The problem is a one-dimensional creep analysis. The top face has a
# pressure load that is a function of time. The creep strain can be
# calculated analytically. There is no practical active linear
# isotropic plasticity because the yield stress for the plasticity
# model is set to 1e30 MPa, which will not be reached in this
# regression test.
#
# The analytic solution to this problem is:
#
# d ec
# ---- = a*S^b with S = c*t^d
# dt
#
# d ec = a*c^b*t^(b*d) dt
#
# a*c^b
# ec = ----- t^(b*d+1)
# b*d+1
#
# where S = stress
# ec = creep strain
# t = time
# a = constant
# b = constant
# c = constant
# d = constant
#
# With a = 3e-24,
# b = 4,
# c = 1,
# d = 1/2, and
# t = 32400
# we have
#
# S = t^(1/2) = 180
#
# ec = 1e-24*t^3 = 3.4012224e-11

#
# 2DRZ Spherical Gap Heat Transfer Test.
#
# This test exercises 2D gap heat transfer for a constant conductivity gap.
#
# The mesh consists of an inner solid sphere of radius = 1 unit, and outer
# hollow sphere with an inner radius of 2. In other words, the gap between
# them is 1 radial unit in length.
#
# The conductivity of both spheres is set very large to achieve a uniform
# temperature in each sphere. The temperature of the center node of the
# inner sphere is ramped from 100 to 200 over one time unit. The
# temperature of the outside of the outer, hollow sphere is held fixed
# at 100.
#
# A simple analytical solution is possible for the integrated heat flux
# between the inner and outer spheres:
#
# Integrated Flux = (T_left - T_right) * (gapK/(r^2*((1/r1)-(1/r2)))) * Area
#
# For gapK = 1 (default value)
#
# The area is taken as the area of the slave (inner) surface:
#
# Area = 4 * pi * 1^2 (4*pi*r^2)
#
# The integrated heat flux across the gap at time 1 is then:
#
# 4*pi*k*delta_T/((1/r1)-(1/r2))
# 4*pi*1*100/((1/1) - (1/2)) = 2513.3 watts
#
# For comparison, see results from the integrated flux post processors.
# This simulation makes use of symmetry, so only 1/2 of the spheres is meshed
# As such, the integrated flux from the post processors is 1/2 of the total,
# or 1256.6 watts... i.e. 400*pi.
# The value coming from the post processor is slightly less than this
# but converges as mesh refinement increases.
#
# Simulating contact is challenging. Regression tests that exercise
# contact features can be difficult to solve consistently across multiple
# platforms. While designing these tests, we felt it worth while to note
# some aspects of these tests. The following applies to:
# sphere3D.i, sphere2DRZ.i, cyl2D.i, and cyl3D.i.
# 1. We decided that to perform consistently across multiple platforms we
# would use very small convergence tolerance. In this test we chose an
# nl_rel_tol of 1e-12.
# 2. Due to such a high value for thermal conductivity (used here so that the
# domains come to a uniform temperature) the integrated flux at time = 0
# was relatively large (the value coming from SideIntegralFlux =
# -_diffusion_coef[_qp]*_grad_u[_qp]*_normals[_qp] where the diffusion coefficient
# here is thermal conductivity).
# Even though _grad_u[_qp] is small, in this case the diffusion coefficient
# is large. The result is a number that isn't exactly zero and tends to
# fail exodiff. For this reason the parameter execute_on = initial should not
# be used. That parameter is left to default settings in these regression tests.

#
# Cavity Pressure Test
#
# This test is designed to compute an internal pressure based on
# p = n * R * T / V
# where
# p is the pressure
# n is the amount of material in the volume (moles)
# R is the universal gas constant
# T is the temperature
# V is the volume
#
# The mesh is composed of one block (1) with an interior cavity of volume 8.
# Block 2 sits in the cavity and has a volume of 1. Thus, the total
# initial volume is 7.
# The test adjusts n, T, and V in the following way:
# n => n0 + alpha * t
# T => T0 + beta * t
# V => V0 + gamma * t
# with
# alpha = n0
# beta = T0 / 2
# gamma = - (0.003322259...) * V0
# T0 = 240.54443866068704
# V0 = 7
# n0 = f(p0)
# p0 = 100
# R = 8.314472 J * K^(-1) * mol^(-1)
#
# So, n0 = p0 * V0 / R / T0 = 100 * 7 / 8.314472 / 240.544439
# = 0.35
#
# The parameters combined at t = 1 gives p = 301.

# 1-D Gap Heat Transfer Test without mechanics
#
# This test exercises 1-D gap heat transfer for a constant conductivity gap.
#
# The mesh consists of two element blocks containing one element each. Each
# element is a unit cube. They sit next to one another with a unit between them.
#
# The conductivity of both blocks is set very large to achieve a uniform temperature
# across each block. The temperature of the far left boundary
# is ramped from 100 to 200 over one time unit. The temperature of the far right
# boundary is held fixed at 100.
#
# A simple analytical solution is possible for the heat flux between the blocks:
#
# Flux = (T_left - T_right) * (gapK/gap_width)
#
# The gap conductivity is specified as 1, thus
#
# gapK(Tavg) = 1.0*Tavg
#
#
# The heat flux across the gap at time = 1 is then:
#
# Flux(2) = 100 * (1.0/1.0) = 100
#
# For comparison, see results from the flux post processors
#
# This test has been augmented with a second scalar field that solves nearly
# the same problem. The conductivity has been changed to 10. Thus, the
# flux for the second field is 1000.

# Test for damped small strain euler beam vibration in y direction
# An impulse load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# density (rho) = 1.0
# mass proportional rayleigh damping(eta) = 0.1
# stiffness proportional rayleigh damping(eta) = 0.1
# HHT time integration parameter (alpha) = -0.3
# Corresponding Newmark beta time integration parameters beta = 0.4225 and gamma = 0.8
# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the behaves like a Euler-Bernoulli beam.
# The displacement time history from this analysis matches with that obtained from Abaqus.
# Values from the first few time steps are as follows:
# time disp_y vel_y accel_y

# Patch Test
# This test is designed to compute constant xx, yy, zz, xy, yz, and zx
# stress on a set of irregular hexes. The mesh is composed of one
# block with seven elements. The elements form a unit cube with one
# internal element. There is a nodeset for each exterior node.
# The cube is displaced by 1e-6 units in x, 2e-6 in y, and 3e-6 in z.
# The faces are sheared as well (1e-6, 2e-6, and 3e-6 for xy, yz, and
# zx). This gives a uniform strain/stress state for all six unique
# tensor components.
# With Young's modulus at 1e6 and Poisson's ratio at 0, the shear
# modulus is 5e5 (G=E/2/(1+nu)). Therefore, for the mechanical strain,
#
# stress xx = 1e6 * 1e-6 = 1
# stress yy = 1e6 * 2e-6 = 2
# stress zz = 1e6 * 3e-6 = 3
# stress xy = 2 * 5e5 * 1e-6 / 2 = 0.5
# (2 * G * gamma_xy / 2 = 2 * G * epsilon_xy)
# stress yz = 2 * 5e5 * 2e-6 / 2 = 1
# stress zx = 2 * 5e5 * 3e-6 / 2 = 1.5
# However, we must also consider the thermal strain.
# The temperature moves 100 degrees, and the coefficient of thermal
# expansion is 1e-8. Therefore, the thermal strain (and the displacement
# since this is a unit cube) is 1e-6.
# Therefore, the overall effect is (at time 1, with a 50 degree delta):
#
# stress xx = 1e6 * (1e-6-0.5e-6) = 0.5
# stress yy = 1e6 * (2e-6-0.5e-6) = 1.5
# stress zz = 1e6 * (3e-6-0.5e-6) = 2.5
# stress xy = 2 * 5e5 * 1e-6 / 2 = 0.5
# (2 * G * gamma_xy / 2 = 2 * G * epsilon_xy)
# stress yz = 2 * 5e5 * 2e-6 / 2 = 1
# stress zx = 2 * 5e5 * 3e-6 / 2 = 1.5
#
# At time 2:
#
# stress xx = 1e6 * (1e-6-1e-6) = 0
# stress yy = 1e6 * (2e-6-1e-6) = 1
# stress zz = 1e6 * (3e-6-1e-6) = 2
# stress xy = 2 * 5e5 * 1e-6 / 2 = 0.5
# (2 * G * gamma_xy / 2 = 2 * G * epsilon_xy)
# stress yz = 2 * 5e5 * 2e-6 / 2 = 1
# stress zx = 2 * 5e5 * 3e-6 / 2 = 1.5

# Patch Test
# This test is designed to compute constant xx, yy, zz, xy, yz, and zx
# stress on a set of irregular hexes. The mesh is composed of one
# block with seven elements. The elements form a unit cube with one
# internal element. There is a nodeset for each exterior node.
# The cube is displaced by 1e-6 units in x, 2e-6 in y, and 3e-6 in z.
# The faces are sheared as well (1e-6, 2e-6, and 3e-6 for xy, yz, and
# zx). This gives a uniform strain/stress state for all six unique
# tensor components.
# With Young's modulus at 1e6 and Poisson's ratio at 0, the shear
# modulus is 5e5 (G=E/2/(1+nu)). Therefore, for the mechanical strain,
#
# stress xx = 1e6 * 1e-6 = 1
# stress yy = 1e6 * 2e-6 = 2
# stress zz = 1e6 * 3e-6 = 3
# stress xy = 2 * 5e5 * 1e-6 / 2 = 0.5
# (2 * G * gamma_xy / 2 = 2 * G * epsilon_xy)
# stress yz = 2 * 5e5 * 2e-6 / 2 = 1
# stress zx = 2 * 5e5 * 3e-6 / 2 = 1.5
# However, we must also consider the thermal strain.
# The temperature moves 100 degrees, and the coefficient of thermal
# expansion is 1e-8. Therefore, the thermal strain (and the displacement
# since this is a unit cube) is 1e-6.
# Therefore, the overall effect is (at time 1, with a 50 degree delta):
#
# stress xx = 1e6 * (1e-6-0.5e-6) = 0.5
# stress yy = 1e6 * (2e-6-0.5e-6) = 1.5
# stress zz = 1e6 * (3e-6-0.5e-6) = 2.5
# stress xy = 2 * 5e5 * 1e-6 / 2 = 0.5
# (2 * G * gamma_xy / 2 = 2 * G * epsilon_xy)
# stress yz = 2 * 5e5 * 2e-6 / 2 = 1
# stress zx = 2 * 5e5 * 3e-6 / 2 = 1.5
#
# At time 2:
#
# stress xx = 1e6 * (1e-6-1e-6) = 0
# stress yy = 1e6 * (2e-6-1e-6) = 1
# stress zz = 1e6 * (3e-6-1e-6) = 2
# stress xy = 2 * 5e5 * 1e-6 / 2 = 0.5
# (2 * G * gamma_xy / 2 = 2 * G * epsilon_xy)
# stress yz = 2 * 5e5 * 2e-6 / 2 = 1

# Element mass tests
# This series of tests is designed to compute the mass of elements based on
# an evolving mass density calculation. The tests consist of expansion and compression
# of the elastic patch test model along each axis, uniform expansion and compression,
# and shear in each direction. The expansion and compression tests change the volume of
# the elements. The corresponding change in density should compensate for this so the
# mass remains constant. The shear tests should not result in a volume change, and this
# is checked too. The mass calculation is done with the post processor called Mass.
# The tests/file names are as follows:
# Expansion and compression along a single axis
# expand_compress_x_test_out.e
# expand_compress_y_test_out.e
# expand_compress_z_test_out.e
# Volumetric expansion and compression
# uniform_expand_compress_test.i
# Zero volume change shear along each axis
# shear_x_test_out.e
# shear_y_test_out.e
# shear_z_test_out.e
# The resulting mass calculation for these tests should always be = 1.
# This test is a duplicate of the uniform_expand_compress_test.i test for solid mechanics, and the
# output of this tensor mechanics test is compared to the original
# solid mechanics output. The duplication is necessary to test the
# migrated tensor mechanics version while maintaining tests for solid mechanics.

#
# This is a test of the piece-wise linear strain hardening model using the
# small strain formulation. This test exercises the temperature-dependent
# hardening curve capability.
#
# Test procedure:
# 1. The element is pulled to and then beyond the yield stress for a given
# temperature.
# 2. The displacement is then constant while the temperature increases and
# the yield stress decreases. This results in a lower stress with more
# plastic strain.
# 3. The temperature decreases beyond its original value giving a higher
# yield stress. The displacement increases, causing increases stress to
# the new yield stress.
# 4. The temperature and yield stress are constant with increasing
# displacement giving a constant stress and more plastic strain.
#
# Plotting total_strain_yy on the x axis and stress_yy on the y axis shows
# the stress history in a clear way.

# This tests the thermal expansion coefficient function using both

# two blocks, each containing a single element, and these use the
# two variants of the function.
# In this test, the instantaneous CTE function has a constant value,
# while the mean CTE function is an analytic function designed to
# give the same response. If \bar{alpha}(T) is the mean CTE function,
# and \alpha(T) is the instantaneous CTE function,
# \bar{\alpha}(T) = 1/(T-Tref) \intA^{T}_{Tsf} \alpha(T) dT
# where Tref is the reference temperature used to define the mean CTE
# function, and Tsf is the stress-free temperature.
# This version of the test uses finite deformation theory.
# The two models produce very similar results. There are slight
# differences due to the large deformation treatment.

#
# This is a test of the piece-wise linear strain hardening model using the
# small strain formulation. This test exercises the temperature-dependent
# yield stress.
#
# Test procedure:
# 1. The element is pulled to and then beyond the yield stress for a given
# temperature.
# 2. The displacement is then constant while the temperature increases and
# the yield stress decreases. This results in a lower stress with more
# plastic strain.
# 3. The temperature decreases beyond its original value giving a higher
# yield stress. The displacement increases, causing increases stress to
# the new yield stress.
# 4. The temperature and yield stress are constant with increasing
# displacement giving a constant stress and more plastic strain.
#
# Plotting total_strain_yy on the x axis and stress_yy on the y axis shows
# the stress history in a clear way.

# Test for small strain Timoshenko beam vibration in y direction
# An impulse load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 2e4
# Shear modulus (G) = 1e4
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 1.0
# Iy = 1.0 = Iz
# Length (L)= 4 m
# density (rho) = 1.0
# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 8
# Therefore, the beam behaves like a Timoshenko beam.
# The FEM solution for this beam with 100 elements give first natural period of 0.2731s with a time step of 0.005.
# The acceleration, velocity and displacement time histories obtained from MOOSE matches with those obtained from ABAQUS.
# Values from the first few time steps are as follows:
# time disp_y vel_y accel_y
# 0.0 0.0 0.0 0.0
# 0.005 2.5473249455812e-05 0.010189299782325 4.0757199129299
# 0.01 5.3012872677486e-05 0.00082654950634483 -7.8208200233219
# 0.015 5.8611622914354e-05 0.0014129505884026 8.055380456145
# 0.02 6.766113649781e-05 0.0022068548449798 -7.7378187535141
# 0.025 7.8981810558437e-05 0.0023214147792709 7.7836427272305
# Note that the theoretical first frequency of the beam using Euler-Bernoulli theory is:
# f1 = 1/(2 pi) * (3.5156/L^2) * sqrt(EI/rho) = 4.9455
# This implies that the corresponding time period of this beam (under Euler-Bernoulli assumption) is 0.2022s.
# This shows that Euler-Bernoulli beam theory under-predicts the time period of a thick beam. In other words, the Euler-Bernoulli beam theory predicts a more compliant beam than reality for a thick beam.

#
# Cavity Pressure Test (Volume input as a vector of postprocessors)
#
# This test is designed to compute an internal pressure based on
# p = n * R * T / V
# where
# p is the pressure
# n is the amount of material in the volume (moles)
# R is the universal gas constant
# T is the temperature
# V is the volume
#
# The mesh is composed of one block (1) with an interior cavity of volume 8.
# Block 2 sits in the cavity and has a volume of 1. Thus, the total
# initial volume is 7.
# The test adjusts n, T, and V in the following way:
# n => n0 + alpha * t
# T => T0 + beta * t
# V => V0 + gamma * t
# with
# alpha = n0
# beta = T0 / 2
# gamma = - (0.003322259...) * V0
# T0 = 240.54443866068704
# V0 = 7
# n0 = f(p0)
# p0 = 100
# R = 8.314472 J * K^(-1) * mol^(-1)
#
# So, n0 = p0 * V0 / R / T0 = 100 * 7 / 8.314472 / 240.544439
# = 0.35
#
# In this test the internal volume is calculated as the sum of two Postprocessors
# internalVolumeInterior and internalVolumeExterior. This sum equals the value
# reported by the internalVolume postprocessor.
#
# The parameters combined at t = 1 gives p = 301.

# Test for rayleigh damping implemented using Newmark time integration
# The test is for an 1-D bar element of unit length fixed on one end
# with a ramped pressure boundary condition applied to the other end.
# zeta and eta correspond to the stiffness and mass proportional
# rayleigh damping beta and gamma are Newmark time integration
# parameters The equation of motion in terms of matrices is:
#
# M*accel + eta*M*vel + zeta*K*vel + K*disp = P*Area
#
# Here M is the mass matrix, K is the stiffness matrix, P is the applied pressure
#
# This equation is equivalent to:
#
# density*accel + eta*density*vel + zeta*d/dt(Div stress) + Div stress = P
#
# The first two terms on the left are evaluated using the Inertial
# force kernel The next two terms on the left involving zeta ise
# evaluated using the StressDivergence Kernel The residual due to
# Pressure is evaluated using Pressure boundary condition
#
# The system will come to steady state slowly after the pressure
# becomes constant.

# ---------------------------------------------------------------------------
# This test is designed to verify the variable elasticity tensor functionality in the
# ADComputeFiniteStrainElasticStress class with the elasticity_tensor_has_changed flag
# by varying the young's modulus with temperature. A constant strain is applied
# to the mesh in this case, and the stress varies with the changing elastic constants.
#
# Geometry: A single element cube in symmetry boundary conditions and pulled
# at a constant displacement to create a constant strain in the x-direction.
#
# Temperature: The temperature varies from 400K to 700K in this simulation by
# 100K each time step. The temperature is held constant in the last
# timestep to ensure that the elasticity tensor components are constant
# under constant temperature.
#
# Results: Because Poisson's ratio is set to zero, only the stress along the x
# axis is non-zero. The stress changes with temperature.
#
# Temperature(K) strain_{xx}(m/m) Young's Modulus(Pa) stress_{xx}(Pa)
# 400 0.001 10.0e6 1.0e4
# 500 0.001 10.0e6 1.0e4
# 600 0.001 9.94e6 9.94e3
# 700 0.001 9.93e6 9.93e3
#
# The tensor mechanics results align exactly with the analytical results above
# when this test is run with ComputeIncrementalSmallStrain. When the test is
# run with ComputeFiniteStrain, a 0.05% discrepancy between the analytical
# strains and the simulation strain results is observed, and this discrepancy
# is carried over into the calculation of the elastic stress.

# Wave propogation in 1D using HHT time integration in the presence of Rayleigh damping
#
# The test is for an 1D bar element of length 4m fixed on one end
# with a sinusoidal pulse dirichlet boundary condition applied to the other end.
# alpha, beta and gamma are HHT time integration parameters
# eta and zeta are mass dependent and stiffness dependent Rayleigh damping
# coefficients, respectively.
# The equation of motion in terms of matrices is:
#
# M*accel + (eta*M+zeta*K)*((1+alpha)*vel-alpha*vel_old)
# +(1+alpha)*K*disp-alpha*K*disp_old = 0
#
# Here M is the mass matrix, K is the stiffness matrix
#
# The displacement at the first, second, third and fourth node at t = 0.1 are

# Hertz Contact: Sphere on sphere
# Spheres have the same radius, Young's modulus, and Poisson's ratio.
# Define E:
# 1/E = (1-nu1^2)/E1 + (1-nu2^2)/E2
#
# Effective radius R:
# 1/R = 1/R1 + 1/R2
#
# F is the applied compressive load.
#
# Area of contact a::
# a^3 = 3FR/4E
#
# Depth of indentation d:
# d = a^2/R
#
#
# Let R1 = R2 = 2. Then R = 1.
#
# Let nu1 = nu2 = 0.25, E1 = E2 = 1.40625e7. Then E = 7.5e6.
#
# Let F = 10000. Then a = 0.1, d = 0.01.
#
## Note: There is not a good way to check the result. The standard approach is
## to map contact pressure as a function of radius, but we don't have the
## contact pressure available. See the description on Wikipedia for details of
## analytic equations, and the Abaqus Benchmarks Manual, 1.1.11, for a plot of
## contact pressure vs. radius.

# Patch Test
# This test is designed to compute constant xx, yy, zz, xy, yz, and zx
# stress on a set of irregular hexes. The mesh is composed of one
# block with seven elements. The elements form a unit cube with one
# internal element. There is a nodeset for each exterior node.
# The cube is displaced by 1e-6 units in x, 2e-6 in y, and 3e-6 in z.
# The faces are sheared as well (1e-6, 2e-6, and 3e-6 for xy, yz, and
# zx). This gives a uniform strain/stress state for all six unique
# tensor components.
# With Young's modulus at 1e6 and Poisson's ratio at 0, the shear
# modulus is 5e5 (G=E/2/(1+nu)). Therefore,
#
# stress xx = 1e6 * 1e-6 = 1
# stress yy = 1e6 * 2e-6 = 2
# stress zz = 1e6 * 3e-6 = 3
# stress xy = 2 * 5e5 * 1e-6 / 2 = 0.5
# (2 * G * gamma_xy / 2 = 2 * G * epsilon_xy)
# stress yz = 2 * 5e5 * 2e-6 / 2 = 1
# stress zx = 2 * 5e5 * 3e-6 / 2 = 1.5

# small, monotonically loaded block of material. If things are working right,
# the predictor should come very close to exactly nailing the solution on steps
# after the first step. Because of nonlinear geometry, the predictor is slightly
# off in general, but that is mitigated by setting this up so that the elements
# undergo no rotations.
# This test checks to see that the predictor is skipped in the last step.

# Test for rayleigh damping implemented using HHT time integration
#
# The test is for an 1-D bar element of unit length fixed on one end
# with a ramped pressure boundary condition applied to the other end.
# zeta and eta correspond to the stiffness and mass proportional
# rayleigh damping alpha, beta and gamma are HHT time integration
# parameters The equation of motion in terms of matrices is:
#
# M*accel + (eta*M+zeta*K)*[(1+alpha)vel-alpha vel_old]
# + alpha*(K*disp - K*disp_old) + K*disp = P(t+alpha dt)*Area
#
# Here M is the mass matrix, K is the stiffness matrix, P is the applied pressure
#
# This equation is equivalent to:
#
# density*accel + eta*density*[(1+alpha)vel-alpha vel_old] +
# zeta*[(1+alpha)*d/dt(Div stress)- alpha*d/dt(Div stress_old)] +
# alpha *(Div stress - Div stress_old) +Div Stress= P(t+alpha dt)
#
# The first two terms on the left are evaluated using the Inertial
# force kernel The next three terms on the left involving zeta and
# alpha are evaluated using the StressDivergence Kernel The residual
# due to Pressure is evaluated using Pressure boundary condition
#
# The system will come to steady state slowly after the pressure
# becomes constant. Alpha equal to zero will result in Newmark
# integration.

# Test for damped small strain euler beam vibration in y direction
# An impulse load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# density (rho) = 1.0
# mass proportional rayleigh damping(eta) = 0.1
# stiffness proportional rayleigh damping(eta) = 0.1
# HHT time integration parameter (alpha) = -0.3
# Corresponding Newmark beta time integration parameters beta = 0.4225 and gamma = 0.8
# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the behaves like a Euler-Bernoulli beam.
# The displacement time history from this analysis matches with that obtained from Abaqus.
# Values from the first few time steps are as follows:
# time disp_y vel_y accel_y
# 0.0 0.0 0.0 0.0
# 0.2 0.019898364318588 0.18838688112273 1.1774180070171

# Patch Test
# This test is designed to compute constant xx, yy, zz, xy, yz, and xz
# stress on a set of irregular hexes. The mesh is composed of one
# block with seven elements. The elements form a unit cube with one
# internal element. There is a nodeset for each exterior node.
# The cube is displaced by 1e-6 units in x, 2e-6 in y, and 3e-6 in z.
# The faces are sheared as well (1e-6, 2e-6, and 3e-6 for xy, yz, and
# zx). This gives a uniform strain/stress state for all six unique
# tensor components. This displacement is again applied in the second
# step.
# With Young's modulus at 1e6 and Poisson's ratio at 0, the shear
# modulus is 5e5 (G=E/2/(1+nu)). Therefore, for the mechanical strain,
#
# stress xx = 1e6 * 1e-6 = 1
# stress yy = 1e6 * 2e-6 = 2
# stress zz = 1e6 * 3e-6 = 3
# stress xy = 2 * 5e5 * 1e-6 / 2 = 0.5
# (2 * G * gamma_xy / 2 = 2 * G * epsilon_xy)
# stress yz = 2 * 5e5 * 2e-6 / 2 = 1
# stress zx = 2 * 5e5 * 3e-6 / 2 = 1.5
# Young's modulus is a function of temperature for this test. The
# temperature changes from 100 to 500. The Young's modulus drops
# due to that temperature change from 1e6 to 6e5.
# Poisson's ratio also is a function of temperature and changes from
# 0 to 0.25.
# At the end of the temperature ramp, E=6e5 and nu=0.25. This gives
# G=2.4e=5. lambda=E*nu/(1+nu)/(1-2*nu)=2.4E5. The final stress
# is therefore
# stress xx = 2.4e5 * 12e-6 + 2*2.4e5*2e-6 = 3.84
# stress yy = 2.4e5 * 12e-6 + 2*2.4e5*4e-6 = 4.80
# stress zz = 2.4e5 * 12e-6 + 2*2.4e5*6e-6 = 5.76
# stress xy = 2 * 2.4e5 * 2e-6 / 2 = 0.48
# (2 * G * gamma_xy / 2 = 2 * G * epsilon_xy)
# stress yz = 2 * 2.4e5 * 4e-6 / 2 = 0.96
# stress xz = 2 * 2.4e5 * 6e-6 / 2 = 1.44

# Truss in two dimensional space
#
# The truss is made of five equilateral triangles supported at each end.
# The truss starts at (0,0). At (1,0), there is a point load of 25.
# The reactions are therefore
# Ryleft = 2/3 * 25 = 16.7
# Ryright = 1/3 * 25 = 8.33
# The area of each member is 0.8.
# Statics gives the stress in each member. For example, for element 6 (from
# (0,0) to (1/2,sqrt(3)/2)), the force is
# f = 2/3 * 25 * 2/sqrt(3) = 100/3/sqrt(3) (compressive)
# and the stress is
# s = -100/3/sqrt(3)/0.8 = -24.06

# Fluid is allowed to leak out from its sides (at x=+/-a)
# The porepressure within the sample is monitored.
#
# As is common in the literature, this is simulated by
# considering the quarter-sample, 0<=x<=a and 0<=y<=b, with
# impermeable, roller BCs at x=0 and y=0 and y=b.
# Porepressure is fixed at zero on x=a.
# Porepressure and displacement are initialised to zero.
# Then the top (y=b) is moved downwards with prescribed velocity,
# so that the total force that is inducing this downwards velocity
# is fixed. The velocity is worked out by solving Mandel's problem
# analytically, and the total force is monitored in the simulation
# to check that it indeed remains constant.
#
# Here are the problem's parameters, and their values:
# Soil width. a = 1
# Soil height. b = 0.1
# Soil's Lame lambda. la = 0.5
# Soil's Lame mu, which is also the Soil's shear modulus. mu = G = 0.75
# Soil bulk modulus. K = la + 2*mu/3 = 1
# Drained Poisson ratio. nu = (3K - 2G)/(6K + 2G) = 0.2
# Soil bulk compliance. 1/K = 1
# Fluid bulk modulus. Kf = 8
# Fluid bulk compliance. 1/Kf = 0.125
# Soil initial porosity. phi0 = 0.1
# Biot coefficient. alpha = 0.6
# Biot modulus. M = 1/(phi0/Kf + (alpha - phi0)(1 - alpha)/K) = 4.705882
# Undrained bulk modulus. Ku = K + alpha^2*M = 2.694118
# Undrained Poisson ratio. nuu = (3Ku - 2G)/(6Ku + 2G) = 0.372627
# Skempton coefficient. B = alpha*M/Ku = 1.048035
# Fluid mobility (soil permeability/fluid viscosity). k = 1.5
# Consolidation coefficient. c = 2*k*B^2*G*(1-nu)*(1+nuu)^2/9/(1-nuu)/(nuu-nu) = 3.821656
# Normal stress on top. F = 1
#
# The solution for porepressure and displacements is given in
# AHD Cheng and E Detournay "A direct boundary element method for plane strain poroelasticity" International Journal of Numerical and Analytical Methods in Geomechanics 12 (1988) 551-572.
# The solution involves complicated infinite series, so I shall not write it here

#
# This is a test of the piece-wise linear strain hardening model using the
# small strain formulation. This test exercises the temperature-dependent
# yield stress.
#
# Test procedure:
# 1. The element is pulled to and then beyond the yield stress for a given
# temperature.
# 2. The displacement is then constant while the temperature increases and
# the yield stress decreases. This results in a lower stress with more
# plastic strain.
# 3. The temperature decreases beyond its original value giving a higher
# yield stress. The displacement increases, causing increases stress to
# the new yield stress.
# 4. The temperature and yield stress are constant with increasing
# displacement giving a constant stress and more plastic strain.
#
# Plotting total_strain_yy on the x axis and stress_yy on the y axis shows
# the stress history in a clear way.

#
# Cavity Pressure Test
#
# This test is designed to compute an internal pressure based on
# p = n * R * T / V
# where
# p is the pressure
# n is the amount of material in the volume (moles)
# R is the universal gas constant
# T is the temperature
# V is the volume
#
# The mesh is composed of one block (1) with an interior cavity of volume 8.
# Block 2 sits in the cavity and has a volume of 1. Thus, the total
# initial volume is 7.
# The test adjusts n, T, and V in the following way:
# n => n0 + alpha * t
# T => T0 + beta * t
# V => V0 + gamma * t
# with
# alpha = n0
# beta = T0 / 2
# gamma = -(0.003322259...) * V0
# T0 = 240.54443866068704
# V0 = 7
# n0 = f(p0)
# p0 = 100
# R = 8.314472 J * K^(-1) * mol^(-1)
#
# So, n0 = p0 * V0 / R / T0 = 100 * 7 / 8.314472 / 240.544439
# = 0.35
#
# The parameters combined at t = 1 gives p = 301.
#
# This test sets the initial temperature to 500, but the CavityPressure
# is told that that initial temperature is T0. Thus, the final solution
# is unchanged.

# Large strain/large rotation cantilever beam test
# A 300 N point load is applied at the end of a 4 m long cantilever beam.
# Young's modulus (E) = 1e4
# Shear modulus (G) = 1e8
# Poisson's ratio (nu) = -0.99995
# shear coefficient (k) = 1.0
# Area (A) = 1.0
# Iy = Iz = 0.16
# The dimensionless parameter alpha = kAGL^2/EI = 1e6
# Since the value of alpha ia quite high, the beam behaves like
# a thin beam where shear effects are not significant.
# Beam deflection:
# small strain+rot = 3.998 m (exact 4.0)
# large strain + small rotation = -0.05 m in x and 3.74 m in z
# large rotations + small strain = -0.92 m in x and 2.38 m in z
# large rotations + large strain = -0.954 m in x and 2.37 m in z (exact -1.0 m in x and 2.4 m in z)

#
# Simple power law creep example (without instantaneous plasticity)
# NOTE: this test is not replicated in a direct tensor mechanics form because the functioning
# of the individual TM power law creep and TM isotropic plasticity is already tested in the
# tensor mechanics module.
#
# The mesh is a 1x1x1 cube with a constant pressure of 10 MPa on the top face.
# Symmetry boundary conditions on three planes provide a uniaxial stress
# field. The temperature is held constant at 1000. The yield stress is set
# at twice the load pressure, thus there is no plasticity. The solution is
# advanced through ten time steps of 0.1 for a total time of 1.
#
# The total strain at time 1 can be computed as:
#
# e_tot = e_elas + e_creep
#
# = P/E + A * sigma**n * exp(-Q/(RT)) * t**m * dt
#
# where P = pressure load
# E = Young's modulus
# A = material parameter
# sigma = stress
# n = power law exponent
# Q = activation energy
# R = gas constant
# T = temperature
# t = time
# m = time hardening exponent
# dt = problem time
#
# For this test, the analytical solutuon is:
#
# e_tot = (10e6/2e11) + 1e-15 * (10e6)**4 * exp(-3e5/(8.3143*1000) * t**0 * 1
# = 5e-5 + 2.136031e-3
# = 2.186031e-3
#
#
# For either linear (formulation = linear) or nonlinear (formulation = nonlinear3d)
# kinematics, PLC_LSH gets:
#
# e_elas = 5e-5
# e_creep = 2.13600e-3
# e_tot = 2.18600e-3
#

# Buckley-Leverett 1-phase.
# The front starts at (around) x=5, and at t=50 it should
# have moved to x=9.6. The version below has a nonzero
# suction function, and at t=50, the front sits between
# (about) x=9.6 and x=9.9. Changing the van-Genuchten
# al parameter to 1E-4 softens the front so it sits between
# (about) x=9.7 and x=10.4, and the simulation runs much faster.
# With al=1E-2 and nx=600, the front sits between x=9.6 and x=9.8,
# but takes about 100 times longer to run.

# Test for rayleigh damping implemented using HHT time integration
#
# The test is for an 1-D bar element of unit length fixed on one end
# with a ramped pressure boundary condition applied to the other end.
# zeta and eta correspond to the stiffness and mass proportional
# rayleigh damping alpha, beta and gamma are HHT time integration
# parameters The equation of motion in terms of matrices is:
#
# M*accel + (eta*M+zeta*K)*[(1+alpha)vel-alpha vel_old]
# + alpha*(K*disp - K*disp_old) + K*disp = P(t+alpha dt)*Area
#
# Here M is the mass matrix, K is the stiffness matrix, P is the applied pressure
#
# This equation is equivalent to:
#
# density*accel + eta*density*[(1+alpha)vel-alpha vel_old] +
# zeta*[(1+alpha)*d/dt(Div stress)- alpha*d/dt(Div stress_old)] +
# alpha *(Div stress - Div stress_old) +Div Stress= P(t+alpha dt)
#
# The first two terms on the left are evaluated using the Inertial
# force kernel The next three terms on the left involving zeta and
# alpha are evaluated using the StressDivergence Kernel The residual
# due to Pressure is evaluated using Pressure boundary condition
#
# The system will come to steady state slowly after the pressure
# becomes constant. Alpha equal to zero will result in Newmark
# integration.

# 1-D Gap Heat Transfer Test without mechanics
#
# This test exercises 1-D gap heat transfer for a constant conductivity gap.
#
# The mesh consists of two element blocks in the x-z plane. Each element block
# is a square. They sit next to one another with a unit between them.
#
# The conductivity of both blocks is set very large to achieve a uniform temperature
# across each block. The temperature of the far bottom boundary
# is ramped from 100 to 200 over one time unit. The temperature of the far top
# boundary is held fixed at 100.
#
# A simple analytical solution is possible for the heat flux between the blocks:
#
# Flux = (T_left - T_right) * (gapK/gap_width)
#
# The gap conductivity is specified as 1, thus
#
# gapK(Tavg) = 1.0*Tavg
#
# The heat flux across the gap at time = 1 is then:
#
# Flux = 100 * (1.0/1.0) = 100
#
# For comparison, see results from the flux post processors. These results
# are the same as for the unit 1-D gap heat transfer between two unit cubes.

#
# loading:
# time : 0.0 0.1 0.2 0.3
# disp : 0.0 0.0 -0.01 -0.01
# This displacement loading is applied using the PresetDisplacement boundary condition.
# Here, the given displacement time history is converted to an acceleration
# time history using Backward Euler time differentiation. Then, the resulting
# acceleration is integrated using Newmark time integration to obtain a
# displacement time history which is then applied to the boundary.
# This is done because if the displacement is applied using Dirichlet BC, the
# resulting acceleration is very noisy.
# Boundaries:
# x = 0 left
# x = 1 right
# y = 0 bottom
# y = 1 top
# z = 0 back
# z = 1 front
# Result: The displacement at the top node in the z direction should match
# the prescribed displacement. Also, the z acceleration should
# be two triangular pulses, one peaking at 0.1 and another peaking at

#
# 1x1x1 unit cube with time-varying pressure on top face
#
# The problem is a one-dimensional creep analysis. The top face has a
# pressure load that is a function of time. The creep strain can be
# calculated analytically. There is no practical active linear
# isotropic plasticity because the yield stress for the plasticity
# model is set to 1e30 MPa, which will not be reached in this
# regression test.
#
# The analytic solution to this problem is:
#
# d ec
# ---- = a*S^b with S = c*t^d
# dt
#
# d ec = a*c^b*t^(b*d) dt
#
# a*c^b
# ec = ----- t^(b*d+1)
# b*d+1
#
# where S = stress
# ec = creep strain
# t = time
# a = constant
# b = constant
# c = constant
# d = constant
#
# With a = 3e-24,
# b = 4,
# c = 1,
# d = 1/2, and
# t = 32400
# we have
#
# S = t^(1/2) = 180
#
# ec = 1e-24*t^3 = 3.4012224e-11

# Test for rayleigh damping implemented using HHT time integration
#
# The test is for an 1D bar element of unit length fixed on one end
# with a ramped pressure boundary condition applied to the other end.
# zeta and eta correspond to the stiffness and mass proportional rayleigh damping
# alpha, beta and gamma are HHT time integration parameters
# The equation of motion in terms of matrices is:
#
# M*accel + (eta*M+zeta*K)*[(1+alpha)vel-alpha vel_old]
# + alpha*(K*disp - K*disp_old) + K*disp = P(t+alpha dt)*Area
#
# Here M is the mass matrix, K is the stiffness matrix, P is the applied pressure
#
# This equation is equivalent to:
#
# density*accel + eta*density*[(1+alpha)vel-alpha vel_old]
# + zeta*[(1+alpha)*d/dt(Div stress)- alpha*d/dt(Div stress_old)]
# + alpha *(Div stress - Div stress_old) +Div Stress= P(t+alpha dt)
#
# The first two terms on the left are evaluated using the Inertial force kernel
# The next three terms on the left involving zeta and alpha are evaluated using
# the DynamicStressDivergenceTensors Kernel
# The residual due to Pressure is evaluated using Pressure boundary condition
#
# The system will come to steady state slowly after the pressure becomes constant.
# Alpha equal to zero will result in Newmark integration.

# Patch Test
# This test is designed to compute constant xx, yy, zz, xy, yz, and zx
# stress on a set of irregular hexes. The mesh is composed of one
# block with seven elements. The elements form a unit cube with one
# internal element. There is a nodeset for each exterior node.
# The cube is displaced by 1e-6 units in x, 2e-6 in y, and 3e-6 in z.
# The faces are sheared as well (1e-6, 2e-6, and 3e-6 for xy, yz, and
# zx). This gives a uniform strain/stress state for all six unique
# tensor components.
# With Young's modulus at 1e6 and Poisson's ratio at 0, the shear
# modulus is 5e5 (G=E/2/(1+nu)). Therefore,
#
# stress xx = 1e6 * 1e-6 = 1
# stress yy = 1e6 * 2e-6 = 2
# stress zz = 1e6 * 3e-6 = 3
# stress xy = 2 * 5e5 * 1e-6 / 2 = 0.5
# (2 * G * gamma_xy / 2 = 2 * G * epsilon_xy)
# stress yz = 2 * 5e5 * 2e-6 / 2 = 1
# stress zx = 2 * 5e5 * 3e-6 / 2 = 1.5

# Test for damped small strain euler beam vibration in y direction
# An impulse load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# density (rho) = 1.0
# mass proportional rayleigh damping(eta) = 0.1
# stiffness proportional rayleigh damping(eta) = 0.1
# HHT time integration parameter (alpha) = -0.3
# Corresponding Newmark beta time integration parameters beta = 0.4225 and gamma = 0.8
# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the behaves like a Euler-Bernoulli beam.
# The displacement time history from this analysis matches with that obtained from Abaqus.

#
# This is a test of the piece-wise linear strain hardening model using the
# small strain formulation. This test exercises the temperature-dependent
# yield stress.
#
# Test procedure:
# 1. The element is pulled to and then beyond the yield stress for a given
# temperature.
# 2. The displacement is then constant while the temperature increases and
# the yield stress decreases. This results in a lower stress with more
# plastic strain.
# 3. The temperature decreases beyond its original value giving a higher
# yield stress. The displacement increases, causing increases stress to
# the new yield stress.
# 4. The temperature and yield stress are constant with increasing
# displacement giving a constant stress and more plastic strain.
#
# Plotting total_strain_yy on the x axis and stress_yy on the y axis shows
# the stress history in a clear way.

# 1-D Gap Heat Transfer Test without mechanics
#
# This test exercises 1-D gap heat transfer for a constant conductivity gap.
#
# The mesh consists of two element blocks in the y-z plane. Each element block
# is a square. They sit next to one another with a unit between them.
#
# The conductivity of both blocks is set very large to achieve a uniform temperature
# across each block. The temperature of the far bottom boundary
# is ramped from 100 to 200 over one time unit. The temperature of the far top
# boundary is held fixed at 100.
#
# A simple analytical solution is possible for the heat flux between the blocks:
#
# Flux = (T_left - T_right) * (gapK/gap_width)
#
# The gap conductivity is specified as 1, thus
#
# gapK(Tavg) = 1.0*Tavg
#
# The heat flux across the gap at time = 1 is then:
#
# Flux = 100 * (1.0/1.0) = 100
#
# For comparison, see results from the flux post processors. These results
# are the same as for the unit 1-D gap heat transfer between two unit cubes.

#
# 1-D spherical Gap Heat Transfer Test
#
# This test exercises 1-D gap heat transfer for a constant conductivity gap.
#
# The mesh consists of two "blocks" with a mesh biased toward the gap
# between them. Each block is unit length. The gap between them is one
# unit in length.
#
# The conductivity of both blocks is set very large to achieve a uniform temperature
# across each block. The temperature of the far left boundary
# is ramped from 100 to 200 over one time unit, and then held fixed for an additional
# time unit. The temperature of the far right boundary is held fixed at 100.
#
# A simple analytical solution is possible for the heat flux between the blocks, or spheres in the case of RSPHERICAL.:
#
# Flux = (T_left - T_right) * (gapK/(r^2*((1/r1)-(1/r2))))
#
# For gapK = 1 (default value)
#
# The area is taken as the area of the slave (inner) surface:
#
# Area = 4 * pi * 1 * 1
#
# The integrated heat flux across the gap at time 2 is then:
#
# 4*pi*k*delta_T/((1/r1)-(1/r2))
# 4*pi*1*100/((1/1) - (1/2)) = 2513.3 watts
#
# For comparison, see results from the flux post processors.

# Patch Test
# This test is designed to compute constant xx, yy, zz, xy, yz, and zx
# stress on a set of irregular hexes. The mesh is composed of one
# block with seven elements. The elements form a unit cube with one
# internal element. There is a nodeset for each exterior node.
# The cube is displaced by 1e-6 units in x, 2e-6 in y, and 3e-6 in z.
# The faces are sheared as well (1e-6, 2e-6, and 3e-6 for xy, yz, and
# zx). This gives a uniform strain/stress state for all six unique
# tensor components.
# With Young's modulus at 1e6 and Poisson's ratio at 0, the shear
# modulus is 5e5 (G=E/2/(1+nu)). Therefore,
#
# stress xx = 1e6 * 1e-6 = 1
# stress yy = 1e6 * 2e-6 = 2
# stress zz = 1e6 * 3e-6 = 3
# stress xy = 2 * 5e5 * 1e-6 / 2 = 0.5
# (2 * G * gamma_xy / 2 = 2 * G * epsilon_xy)
# stress yz = 2 * 5e5 * 2e-6 / 2 = 1
# stress zx = 2 * 5e5 * 3e-6 / 2 = 1.5

# Test for HHT time integration
# The test is for an 1D bar element of unit length fixed on one end
# with a ramped pressure boundary condition applied to the other end.
# alpha, beta and gamma are HHT time integration parameters
# The equation of motion in terms of matrices is:
#
# M*accel + alpha*(K*disp - K*disp_old) + K*disp = P(t+alpha dt)*Area
#
# Here M is the mass matrix, K is the stiffness matrix, P is the applied pressure
#
# This equation is equivalent to:
#
# density*accel + alpha*(Div stress - Div stress_old) +Div Stress= P(t+alpha dt)
#
# The first term on the left is evaluated using the Inertial force kernel
# The next two terms on the left involving alpha are evaluated using the
# DynamicStressDivergenceTensors Kernel
# The residual due to Pressure is evaluated using Pressure boundary condition
#
# The system will come to steady state slowly after the pressure becomes constant.
# Alpha equal to zero will result in Newmark integration.

# Patch Test
# This test is designed to compute displacements from a thermal strain.
# The cube is displaced by 1e-6 units in x, 2e-6 in y, and 3e-6 in z.
# The faces are sheared as well (1e-6, 2e-6, and 3e-6 for xy, yz, and
# zx). This gives a uniform strain/stress state for all six unique
# tensor components.
# The temperature moves 100 degrees, and the coefficient of thermal
# expansion is 1e-6. Therefore, the strain (and the displacement
# since this is a unit cube) is 1e-4.

# One 3D element under ramped displacement loading.
#
# loading:
# time : 0.0 0.1 0.2 0.3
# disp : 0.0 0.0 -0.01 -0.01
# This displacement loading is applied using the PresetDisplacement boundary condition.
# Here, the given displacement time history is converted to an acceleration
# time history using Backward Euler time differentiation. Then, the resulting
# acceleration is integrated using Newmark time integration to obtain a
# displacement time history which is then applied to the boundary.
# This is done because if the displacement is applied using Dirichlet BC, the
# resulting acceleration is very noisy.
# Boundaries:
# x = 0 left
# x = 1 right
# y = 0 bottom
# y = 1 top
# z = 0 back
# z = 1 front
# Result: The displacement at the top node in the z direction should match
# the prescribed displacement. Also, the z acceleration should
# be two triangular pulses, one peaking at 0.1 and another peaking at
# 0.2.

modules/combined/test/tests/evolving_mass_density/uniform_expand_compress_test_tensors.i
# Element mass tests
# This series of tests is designed to compute the mass of elements based on
# an evolving mass density calculation. The tests consist of expansion and compression
# of the elastic patch test model along each axis, uniform expansion and compression,
# and shear in each direction. The expansion and compression tests change the volume of
# the elements. The corresponding change in density should compensate for this so the
# mass remains constant. The shear tests should not result in a volume change, and this
# is checked too. The mass calculation is done with the post processor called Mass.
# The tests/file names are as follows:
# Expansion and compression along a single axis
# expand_compress_x_test_out.e
# expand_compress_y_test_out.e
# expand_compress_z_test_out.e
# Volumetric expansion and compression
# uniform_expand_compress_test.i
# Zero volume change shear along each axis
# shear_x_test_out.e
# shear_y_test_out.e
# shear_z_test_out.e
# The resulting mass calculation for these tests should always be = 1.
# This test is a duplicate of the uniform_expand_compress_test.i test for solid mechanics, and the
# output of this tensor mechanics test is compared to the original
# solid mechanics output. The duplication is necessary to test the
# migrated tensor mechanics version while maintaining tests for solid mechanics.

# Patch Test
# This test is designed to compute displacements from a thermal strain.
# The cube is displaced by 1e-6 units in x, 2e-6 in y, and 3e-6 in z.
# The faces are sheared as well (1e-6, 2e-6, and 3e-6 for xy, yz, and
# zx). This gives a uniform strain/stress state for all six unique
# tensor components.
# The temperature moves 100 degrees, and the coefficient of thermal
# expansion is 1e-6. Therefore, the strain (and the displacement
# since this is a unit cube) is 1e-4.

# This tests the thermal expansion coefficient function using both
# options to specify that function: mean and instantaneous. There
# two blocks, each containing a single element, and these use the
# two variants of the function.
# In this test, the instantaneous CTE function is a linear function
# while the mean CTE function is an analytic function designed to
# give the same response. If \bar{alpha}(T) is the mean CTE function,
# and \alpha(T) is the instantaneous CTE function,
# \bar{\alpha}(T) = 1/(T-Tref) \intA^{T}_{Tsf} \alpha(T) dT
# where Tref is the reference temperature used to define the mean CTE
# function, and Tsf is the stress-free temperature.
# This version of the test uses finite deformation theory.
# The two models produce very similar results. There are slight
# differences due to the large deformation treatment.

#
# Cavity Pressure Test
#
# This test is designed to compute an internal pressure based on
# p = n * R * T / V
# where
# p is the pressure
# n is the amount of material in the volume (moles)
# R is the universal gas constant
# T is the temperature
# V is the volume
#
# The mesh is composed of one block (1) with an interior cavity of volume 8.
# Block 2 sits in the cavity and has a volume of 1. Thus, the total
# initial volume is 7.
# The test adjusts n, T, and V in the following way:
# n => n0 + alpha * t
# T => T0 + beta * t
# V => V0 + gamma * t
# with
# alpha = n0
# beta = T0 / 2
# gamma = -(0.003322259...) * V0
# T0 = 240.54443866068704
# V0 = 7
# n0 = f(p0)
# p0 = 100
# R = 8.314472 J * K^(-1) * mol^(-1)
#
# So, n0 = p0 * V0 / R / T0 = 100 * 7 / 8.314472 / 240.544439
# = 0.35
#
# The parameters combined at t = 1 gives p = 301.
#
# This test sets the initial temperature to 500, but the CavityPressure
# is told that that initial temperature is T0. Thus, the final solution
# is unchanged.

# Test for rayleigh damping implemented using Newmark time integration
# The test is for an 1-D bar element of unit length fixed on one end
# with a ramped pressure boundary condition applied to the other end.
# zeta and eta correspond to the stiffness and mass proportional
# rayleigh damping beta and gamma are Newmark time integration
# parameters The equation of motion in terms of matrices is:
#
# M*accel + eta*M*vel + zeta*K*vel + K*disp = P*Area
#
# Here M is the mass matrix, K is the stiffness matrix, P is the applied pressure
#
# This equation is equivalent to:
#
# density*accel + eta*density*vel + zeta*d/dt(Div stress) + Div stress = P
#
# The first two terms on the left are evaluated using the Inertial
# force kernel The next two terms on the left involving zeta ise
# evaluated using the StressDivergence Kernel The residual due to
# Pressure is evaluated using Pressure boundary condition
#
# The system will come to steady state slowly after the pressure
# becomes constant.

# mass = 2.0 at the fixed end (just for file testing purposes does not alter result)
# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the beam behaves like a Euler-Bernoulli beam.
# The theoretical first frequency of this beam is:
# f1 = 1/(2 pi) * sqrt(3EI/(mL^3)) = 0.25
# This implies that the corresponding time period of this beam is 4s.
# The FEM solution for this beam with 10 element gives time periods of 4s with time step of 0.01s.
# A higher time step of 0.1 s is used in the test to reduce computational time.
# The time history from this analysis matches with that obtained from Abaqus.
# Values from the first few time steps are as follows:
# time disp_y vel_y accel_y
# 0.0 0.0 0.0 0.0
# 0.1 0.0013076435060869 0.026152870121738 0.52305740243477

# 1-D Gap Heat Transfer Test without mechanics
#
# This test exercises 1-D gap heat transfer for a constant conductivity gap.
#
# The mesh consists of two element blocks in the x-y plane. Each element block
# is a square. They sit next to one another with a unit between them.
#
# The conductivity of both blocks is set very large to achieve a uniform temperature
# across each block. The temperature of the far bottom boundary
# is ramped from 100 to 200 over one time unit. The temperature of the far top
# boundary is held fixed at 100.
#
# A simple analytical solution is possible for the heat flux between the blocks:
#
# Flux = (T_left - T_right) * (gapK/gap_width)
#
# The gap conductivity is specified as 1, thus
#
# gapK(Tavg) = 1.0*Tavg
#
# The heat flux across the gap at time = 1 is then:
#
# Flux = 100 * (1.0/1.0) = 100
#
# For comparison, see results from the flux post processors. These results
# are the same as for the unit 1-D gap heat transfer between two unit cubes.

#
# This test checks elastic stress calculations with mechanical and thermal
# strain using small strain formulation. Young's modulus is 3600, and Poisson's ratio is 0.2.
# The axisymmetric, plane strain 1D mesh is pulled with 1e-6 strain. Thus,
# the strain is [1e-6, 0, 1e-6] (xx, yy, zz). This gives stress of
# [5e-3, 2e-3, 5e-3]. After a temperature increase of 100 with alpha of
# 1e-8, the stress becomes [-1e-3, -4e-3, -1e-3].

# This test exercises the linear strain hardening material. The mesh is
# taken from the patch test (7 elements, 1 on the interior). There are
# symmetry bcs on three faces with a pressure load on another face.
#
# Young's modulus = 2.4e5
# Yield stress = 2.4e2
# Hardening constant = 1600
#
# The pressure reaches 2.4e2 at time 1 and 2.6e2 at time 2. Thus, at
# time 1, the stress is at the yield stress. 2.4e2/2.4e5=0.001 (the
# strain at time 1). The increase in stress from time 1 to time 2 is
# 20. 20/1600=0.0125 (the plastic strain). The elastic strain at
# time 2 is 260/2.4e5=0.00108333. The total strain at time 2 is
# 0.01358333.

# ---------------------------------------------------------------------------
# This test is designed to verify the variable elasticity tensor functionality in the
# ComputeFiniteStrainElasticStress class with the elasticity_tensor_has_changed flag
# by varying the young's modulus with temperature. A constant strain is applied
# to the mesh in this case, and the stress varies with the changing elastic constants.
#
# Geometry: A single element cube in symmetry boundary conditions and pulled
# at a constant displacement to create a constant strain in the x-direction.
#
# Temperature: The temperature varies from 400K to 700K in this simulation by
# 100K each time step. The temperature is held constant in the last
# timestep to ensure that the elasticity tensor components are constant
# under constant temperature.
#
# Results: Because Poisson's ratio is set to zero, only the stress along the x
# axis is non-zero. The stress changes with temperature.
#
# Temperature(K) strain_{xx}(m/m) Young's Modulus(Pa) stress_{xx}(Pa)
# 400 0.001 10.0e6 1.0e4
# 500 0.001 10.0e6 1.0e4
# 600 0.001 9.94e6 9.94e3
# 700 0.001 9.93e6 9.93e3
#
# The tensor mechanics results align exactly with the analytical results above
# when this test is run with ComputeIncrementalSmallStrain. When the test is
# run with ComputeFiniteStrain, a 0.05% discrepancy between the analytical
# strains and the simulation strain results is observed, and this discrepancy
# is carried over into the calculation of the elastic stress.

# Test for HHT time integration
# The test is for an 1D bar element of unit length fixed on one end
# with a ramped pressure boundary condition applied to the other end.
# alpha, beta and gamma are HHT time integration parameters
# The equation of motion in terms of matrices is:
#
# M*accel + alpha*(K*disp - K*disp_old) + K*disp = P(t+alpha dt)*Area
#
# Here M is the mass matrix, K is the stiffness matrix, P is the applied pressure
#
# This equation is equivalent to:
#
# density*accel + alpha*(Div stress - Div stress_old) +Div Stress= P(t+alpha dt)
#
# The first term on the left is evaluated using the Inertial force kernel
# The next two terms on the left involving alpha are evaluated using the
# DynamicStressDivergenceTensors Kernel
# The residual due to Pressure is evaluated using Pressure boundary condition
#
# The system will come to steady state slowly after the pressure becomes constant.
# Alpha equal to zero will result in Newmark integration.

# This test checks the generalized plane strain using incremental small strain formulation.
# The model consists of two sets of line elements. One undergoes a temperature rise of 100 with
# the other seeing a temperature rise of 300. Young's modulus is 3600, and
# Poisson's ratio is 0.2. The thermal expansion coefficient is 1e-8. All
# nodes are constrained against movement.
#
# For plane strain case, i.e., without constraining the strain_yy to be uniform,
# the stress solution would be [-6e-3, -6e-3, -6e-3] and [-18e-3, -18e-3, -18e-3] (xx, yy, zz).
# The generalized plane strain kernels work to balance the force in y direction.
#
# With out of plane strain of 3e-6, the stress solution becomes
# [-3e-3, 6e-3, -3e-3] and [-15e-3, -6e-3, -15e-3] (xx, yy, zz). This gives
# a domain integral of out-of-plane stress to be zero.

#
# Simple power law creep example (without instantaneous plasticity).
# NOTE: this test is not replicated in a direct tensor mechanics form because the functioning
# of the individual TM power law creep and TM isotropic plasticity is already tested in the
# tensor mechanics module.
#
# The mesh is a 1x1x1 cube with a constant pressure of 10 MPa on the top face.
# Symmetry boundary conditions on three planes provide a uniaxial stress
# field. The temperature is held constant at 1000. The yield stress is set
# at twice the load pressure, thus there is no plasticity. The solution is
# advanced through ten time steps of 0.1 for a total time of 1.
#
# The total strain at time 1 can be computed as:
#
# e_tot = e_elas + e_creep
#
# = P/E + A * sigma**n * exp(-Q/(RT)) * t**m * dt
#
# where P = pressure load
# E = Young's modulus
# A = material parameter
# sigma = stress
# n = power law exponent
# Q = activation energy
# R = gas constant
# T = temperature
# t = time
# m = time hardening exponent
# dt = problem time
#
# For this test, the analytical solutuon is:
#
# e_tot = (10e6/2e11) + 1e-15 * (10e6)**4 * exp(-3e5/(8.3143*1000) * t**0 * 1
# = 5e-5 + 2.136031e-3
# = 2.186031e-3
#
#
# For either linear (formulation = linear) or nonlinear (formulation = nonlinear3d)
# kinematics, PLC_LSH gets:
#
# e_elas = 5e-5
# e_creep = 2.13600e-3
# e_tot = 2.18600e-3

# Mandel's problem of consolodation of a drained medium
#
# A sample is in plane strain.
# -a <= x <= a
# -b <= y <= b
# It is squashed with constant force by impermeable, frictionless plattens on its top and bottom surfaces (at y=+/-b)
# Fluid is allowed to leak out from its sides (at x=+/-a)
# The porepressure within the sample is monitored.
#
# As is common in the literature, this is simulated by
# considering the quarter-sample, 0<=x<=a and 0<=y<=b, with
# impermeable, roller BCs at x=0 and y=0 and y=b.
# Porepressure is fixed at zero on x=a.
# Porepressure and displacement are initialised to zero.
# Then the top (y=b) is moved downwards with prescribed velocity,
# so that the total force that is inducing this downwards velocity
# is fixed. The velocity is worked out by solving Mandel's problem
# analytically, and the total force is monitored in the simulation
# to check that it indeed remains constant.
#
# Here are the problem's parameters, and their values:
# Soil width. a = 1
# Soil height. b = 0.1
# Soil's Lame lambda. la = 0.5
# Soil's Lame mu, which is also the Soil's shear modulus. mu = G = 0.75
# Soil bulk modulus. K = la + 2*mu/3 = 1
# Drained Poisson ratio. nu = (3K - 2G)/(6K + 2G) = 0.2
# Soil bulk compliance. 1/K = 1
# Fluid bulk modulus. Kf = 8
# Fluid bulk compliance. 1/Kf = 0.125
# Soil initial porosity. phi0 = 0.1
# Biot coefficient. alpha = 0.6
# Biot modulus. M = 1/(phi0/Kf + (alpha - phi0)(1 - alpha)/K) = 4.705882
# Undrained bulk modulus. Ku = K + alpha^2*M = 2.694118
# Undrained Poisson ratio. nuu = (3Ku - 2G)/(6Ku + 2G) = 0.372627
# Skempton coefficient. B = alpha*M/Ku = 1.048035
# Fluid mobility (soil permeability/fluid viscosity). k = 1.5
# Consolidation coefficient. c = 2*k*B^2*G*(1-nu)*(1+nuu)^2/9/(1-nuu)/(nuu-nu) = 3.821656
# Normal stress on top. F = 1
#
# The solution for porepressure and displacements is given in
# AHD Cheng and E Detournay "A direct boundary element method for plane strain poroelasticity" International Journal of Numerical and Analytical Methods in Geomechanics 12 (1988) 551-572.
# The solution involves complicated infinite series, so I shall not write it here
#
# FINAL NOTE: The above solution assumes constant Biot Modulus.
# In porous_flow this is not true. Therefore the solution is
# a little different than in the paper. This test was therefore
# validated against MOOSE's poromechanics, which can choose either
# a constant Biot Modulus (which has been shown to agree with
# the analytic solution), or a non-constant Biot Modulus (which
# gives the same results as porous_flow).

# This simulation uses the piece-wise linear strain hardening model
# with the incremental small strain formulation; incremental small strain
# is required to produce the strain_increment for the DiscreteRadialReturnStressIncrement
# class, which handles the calculation of the stress increment to return
# to the yield surface in a J2 (isotropic) plasticity problem.
#
# This test assumes a Poissons ratio of zero and applies a displacement loading
# condition on the top in the y direction while fixing the displacement in the x
# and z directions; thus, only the normal stress and the normal strains in the
# y direction are compared in this problem.
#
# A similar problem was run in Abaqus on a similar 1 element mesh and was used
# to verify the SolidMechanics solution; this TensorMechanics code matches the
# SolidMechanics solution.
#
# Mechanical strain is the sum of the elastic and plastic strains but is different
# from total strain in cases with eigen strains, e.g. thermal strain.

# Test for Newmark time integration
# The test is for an 1D bar element of unit length fixed on one end
# with a ramped pressure boundary condition applied to the other end.
# beta and gamma are Newmark time integration parameters
# The equation of motion in terms of matrices is:
#
# M*accel + K*disp = P*Area
#
# Here M is the mass matrix, K is the stiffness matrix, P is the applied pressure
#
# This equation is equivalent to:
#
# density*accel + Div Stress = P
#
# The first term on the left is evaluated using the Inertial force kernel
# The last term on the left is evaluated using StressDivergenceTensors
# The residual due to Pressure is evaluated using Pressure boundary condition

# This is a basic test of the system for continuum damage mechanics
# materials. It uses ScalarMaterialDamage for the damage model,
# which simply gets its damage index from another material. In this
# case, we prescribe the evolution of the damage index using a
# function. A single element has a fixed prescribed displacement
# on one side that puts the element in tension, and then the
# damage index evolves from 0 to 1 over time, and this verifies
# that the stress correspondingly drops to 0.

# This tests the thermal expansion coefficient function using both
# options to specify that function: mean and instantaneous. There
# two blocks, each containing a single element, and these use the
# two variants of the function.
# In this test, the instantaneous CTE function has a constant value,
# while the mean CTE function is an analytic function designed to
# give the same response. If \bar{alpha}(T) is the mean CTE function,
# and \alpha(T) is the instantaneous CTE function,
# \bar{\alpha}(T) = 1/(T-Tref) \intA^{T}_{Tsf} \alpha(T) dT
# where Tref is the reference temperature used to define the mean CTE
# function, and Tsf is the stress-free temperature.
# This version of the test uses small deformation theory. The results
# from the two models are identical.

# This tests the thermal expansion coefficient function using both

# two blocks, each containing a single element, and these use the
# two variants of the function.
# In this test, the instantaneous CTE function is a linear function
# while the mean CTE function is an analytic function designed to
# give the same response. If \bar{alpha}(T) is the mean CTE function,
# and \alpha(T) is the instantaneous CTE function,
# \bar{\alpha}(T) = 1/(T-Tref) \intA^{T}_{Tsf} \alpha(T) dT
# where Tref is the reference temperature used to define the mean CTE
# function, and Tsf is the stress-free temperature.
# This version of the test uses small deformation theory. The results

# Mandel's problem of consolodation of a drained medium
# Using the FullySaturatedDarcyBase and FullySaturatedFullySaturatedMassTimeDerivative kernels
# with multiply_by_density = false, so that this problem becomes linear
# Note the use of consistent_with_displaced_mesh = false in the calculation of volumetric strain
#
# A sample is in plane strain.
# -a <= x <= a
# -b <= y <= b
# It is squashed with constant force by impermeable, frictionless plattens on its top and bottom surfaces (at y=+/-b)
# Fluid is allowed to leak out from its sides (at x=+/-a)
# The porepressure within the sample is monitored.
#
# As is common in the literature, this is simulated by
# considering the quarter-sample, 0<=x<=a and 0<=y<=b, with
# impermeable, roller BCs at x=0 and y=0 and y=b.
# Porepressure is fixed at zero on x=a.
# Porepressure and displacement are initialised to zero.
# Then the top (y=b) is moved downwards with prescribed velocity,
# so that the total force that is inducing this downwards velocity
# is fixed. The velocity is worked out by solving Mandel's problem
# analytically, and the total force is monitored in the simulation
# to check that it indeed remains constant.
#
# Here are the problem's parameters, and their values:
# Soil width. a = 1
# Soil height. b = 0.1
# Soil's Lame lambda. la = 0.5
# Soil's Lame mu, which is also the Soil's shear modulus. mu = G = 0.75
# Soil bulk modulus. K = la + 2*mu/3 = 1
# Drained Poisson ratio. nu = (3K - 2G)/(6K + 2G) = 0.2
# Soil bulk compliance. 1/K = 1
# Fluid bulk modulus. Kf = 8
# Fluid bulk compliance. 1/Kf = 0.125
# Soil initial porosity. phi0 = 0.1
# Biot coefficient. alpha = 0.6
# Biot modulus. M = 1/(phi0/Kf + (alpha - phi0)(1 - alpha)/K) = 4.705882
# Undrained bulk modulus. Ku = K + alpha^2*M = 2.694118
# Undrained Poisson ratio. nuu = (3Ku - 2G)/(6Ku + 2G) = 0.372627
# Skempton coefficient. B = alpha*M/Ku = 1.048035
# Fluid mobility (soil permeability/fluid viscosity). k = 1.5
# Consolidation coefficient. c = 2*k*B^2*G*(1-nu)*(1+nuu)^2/9/(1-nuu)/(nuu-nu) = 3.821656
# Normal stress on top. F = 1
#
# The solution for porepressure and displacements is given in
# AHD Cheng and E Detournay "A direct boundary element method for plane strain poroelasticity" International Journal of Numerical and Analytical Methods in Geomechanics 12 (1988) 551-572.
# The solution involves complicated infinite series, so I shall not write it here

#
# 3D Spherical Gap Heat Transfer Test.
#
# This test exercises 3D gap heat transfer for a constant conductivity gap.
#
# The mesh consists of an inner solid sphere of radius = 1 unit, and outer
# hollow sphere with an inner radius of 2. In other words, the gap between
# them is 1 radial unit in length.
#
# The conductivity of both spheres is set very large to achieve a uniform
# temperature in each sphere. The temperature of the center node of the
# inner sphere is ramped from 100 to 200 over one time unit. The
# temperature of the outside of the outer, hollow sphere is held fixed
# at 100.
#
# A simple analytical solution is possible for the integrated heat flux
# between the inner and outer spheres:
#
# Integrated Flux = (T_left - T_right) * (gapK/(r^2*((1/r1)-(1/r2)))) * Area
#
# For gapK = 1 (default value)
#
# The area is taken as the area of the slave (inner) surface:
#
# Area = 4 * pi * 1^2 (4*pi*r^2)
#
# The integrated heat flux across the gap at time 1 is then:
#
# 4*pi*k*delta_T/((1/r1)-(1/r2))
# 4*pi*1*100/((1/1) - (1/2)) = 2513.3 watts
#
# For comparison, see results from the integrated flux post processors.
# This simulation makes use of symmetry, so only 1/8 of the spheres is meshed
# As such, the integrated flux from the post processors is 1/8 of the total,
# or 314.159 watts... i.e. 100*pi.
# The value coming from the post processor is slightly less than this
# but converges as mesh refinement increases.
#
# Simulating contact is challenging. Regression tests that exercise
# contact features can be difficult to solve consistently across multiple
# platforms. While designing these tests, we felt it worth while to note
# some aspects of these tests. The following applies to:
# sphere3D.i, sphere2DRZ.i, cyl2D.i, and cyl3D.i.
# 1. We decided that to perform consistently across multiple platforms we
# would use very small convergence tolerance. In this test we chose an
# nl_rel_tol of 1e-12.
# 2. Due to such a high value for thermal conductivity (used here so that the
# domains come to a uniform temperature) the integrated flux at time = 0
# was relatively large (the value coming from SideIntegralFlux =
# -_diffusion_coef[_qp]*_grad_u[_qp]*_normals[_qp] where the diffusion coefficient
# here is thermal conductivity).
# Even though _grad_u[_qp] is small, in this case the diffusion coefficient
# is large. The result is a number that isn't exactly zero and tends to
# fail exodiff. For this reason the parameter execute_on = initial should not
# be used. That parameter is left to default settings in these regression tests.

# Test for Acceleration boundary condition
# This test contains one brick element which is fixed in the y and z direction.
# Base acceleration is applied in the x direction to all nodes on the bottom surface (y=0).
# The PresetAcceleration converts the given acceleration to a displacement
# using Newmark time integration. This displacement is then prescribed on the boundary.
#
# Result: The acceleration at the bottom node should be same as the input acceleration
# which is a triangular function with peak at t = 0.2 in this case. Width of the triangular function

#
# Cavity Pressure Test
#
# This test is designed to compute an internal pressure based on
# p = n * R * T / V
# where
# p is the pressure
# n is the amount of material in the volume (moles)
# R is the universal gas constant
# T is the temperature
# V is the volume
#
# The mesh is composed of one block (2) with an interior cavity of volume 8.
# Block 1 sits in the cavity and has a volume of 1. Thus, the total
# initial volume is 7.
# The test adjusts T in the following way:
# T => T0 + beta * t
# with
# beta = T0
# T0 = 240.54443866068704
# V0 = 7
# n0 = f(p0)
# p0 = 100
# R = 8.314472 J * K^(-1) * mol^(-1)
#
# So, n0 = p0 * V0 / R / T0 = 100 * 7 / 8.314472 / 240.544439
# = 0.35
#
# At t = 1, p = 200.

# This test assumes a Poissons ratio of 0.3 and applies a displacement loading

#
# An identical problem was run in Abaqus on a similar 1 element mesh and was used

# This test contains one brick element which is fixed in the y and z direction.
# Base acceleration is applied in the x direction to all nodes on the bottom surface (y=0).
# The PresetAcceleration converts the given acceleration to a displacement
# using Newmark time integration. This displacement is then prescribed on the boundary.
#
# Result: The acceleration at the bottom node should be same as the input acceleration
# which is a triangular function with peak at t = 0.2 in this case. Width of the triangular function
# is 0.2 s.

# Test for HHT time integration
# The test is for an 1-D bar element of unit length fixed on one end
# with a ramped pressure boundary condition applied to the other end.
# alpha, beta and gamma are HHT time integration parameters The
# equation of motion in terms of matrices is:
#
# M*accel + alpha*(K*disp - K*disp_old) + K*disp = P(t+alpha dt)*Area
#
# Here M is the mass matrix, K is the stiffness matrix, P is the applied pressure
#
# This equation is equivalent to:
#
# density*accel + alpha*(Div stress - Div stress_old) +Div Stress= P(t+alpha dt)
#
# The first term on the left is evaluated using the Inertial force
# kernel The next two terms on the left involving alpha is evaluated
# using the StressDivergence Kernel The residual due to Pressure is
# evaluated using Pressure boundary condition
#
# The system will come to steady state slowly after the pressure
# becomes constant. Alpha equal to zero will result in Newmark
# integration.

# This tests the thermal expansion coefficient function using both
# options to specify that function: mean and instantaneous. There
# two blocks, each containing a single element, and these use the
# two variants of the function.
# In this test, the instantaneous CTE function is a linear function
# while the mean CTE function is an analytic function designed to
# give the same response. If \bar{alpha}(T) is the mean CTE function,
# and \alpha(T) is the instantaneous CTE function,
# \bar{\alpha}(T) = 1/(T-Tref) \intA^{T}_{Tsf} \alpha(T) dT
# where Tref is the reference temperature used to define the mean CTE
# function, and Tsf is the stress-free temperature.
# This version of the test uses finite deformation theory.
# The two models produce very similar results. There are slight
# differences due to the large deformation treatment.

#
# This test checks the generalized plane strain using small strain formulation.
# The model consists of two sets of line elements. One undergoes a temperature rise of 100 with
# the other seeing a temperature rise of 300. Young's modulus is 3600, and
# Poisson's ratio is 0.2. The thermal expansion coefficient is 1e-8. All
# nodes are constrained against movement.
#
# For plane strain case, i.e., without constraining the strain_yy to be uniform,
# the stress solution would be [-6e-3, -6e-3, -6e-3] and [-18e-3, -18e-3, -18e-3] (xx, yy, zz).
# The generalized plane strain kernels work to balance the force in y direction.
#
# With out of plane strain of 3e-6, the stress solution becomes
# [-3e-3, 6e-3, -3e-3] and [-15e-3, -6e-3, -15e-3] (xx, yy, zz). This gives
# a domain integral of out-of-plane stress to be zero.

# p is the pressure
# n is the amount of material in the volume (moles)
# R is the universal gas constant
# T is the temperature
# V is the volume
#
# The mesh is composed of one block (2) with an interior cavity of volume 8.
# Block 1 sits in the cavity and has a volume of 1. Thus, the total
# initial volume is 7.
# The test adjusts T in the following way:
# T => T0 + beta * t
# with
# beta = T0
# T0 = 240.54443866068704
# V0 = 7
# n0 = f(p0)
# p0 = 100
# R = 8.314472 J * K^(-1) * mol^(-1)
#
# So, n0 = p0 * V0 / R / T0 = 100 * 7 / 8.314472 / 240.544439
# = 0.35
#
# At t = 1, p = 200.

# small, monotonically loaded block of material. If things are working right,
# the predictor should come very close to exactly nailing the solution on steps
# after the first step. Because of nonlinear geometry, the predictor is slightly
# off in general, but that is mitigated by setting this up so that the elements
# undergo no rotations.
# The main thing to check here is that once the predictor kicks in, there are

#
# This test exercises the linear strain hardening material. The mesh is
# taken from the patch test (7 elements, 1 on the interior). There are
# symmetry bcs on three faces with a pressure load on another face.
#
# Young's modulus = 2.4e5
# Yield stress = 2.4e2
# Hardening constant = 1600
#
# The pressure reaches 2.4e2 at time 1 and 2.6e2 at time 2. Thus, at
# time 1, the stress is at the yield stress. 2.4e2/2.4e5=0.001 (the
# strain at time 1). The increase in stress from time 1 to time 2 is
# 20. 20/1600=0.0125 (the plastic strain). The elastic strain at
# time 2 is 260/2.4e5=0.00108333. The total strain at time 2 is
# 0.01358333.

# Test for HHT time integration
# The test is for an 1-D bar element of unit length fixed on one end
# with a ramped pressure boundary condition applied to the other end.
# alpha, beta and gamma are HHT time integration parameters The
# equation of motion in terms of matrices is:
#
# M*accel + alpha*(K*disp - K*disp_old) + K*disp = P(t+alpha dt)*Area
#
# Here M is the mass matrix, K is the stiffness matrix, P is the applied pressure
#
# This equation is equivalent to:
#
# density*accel + alpha*(Div stress - Div stress_old) +Div Stress= P(t+alpha dt)
#
# The first term on the left is evaluated using the Inertial force
# kernel The next two terms on the left involving alpha is evaluated
# using the StressDivergence Kernel The residual due to Pressure is
# evaluated using Pressure boundary condition
#
# The system will come to steady state slowly after the pressure
# becomes constant. Alpha equal to zero will result in Newmark
# integration.

modules/combined/test/tests/gap_heat_transfer_htonly/cyl3D.i
#
# 3D Cylindrical Gap Heat Transfer Test.
#
# This test exercises 3D gap heat transfer for a constant conductivity gap.
#
# The mesh consists of an inner solid cylinder of radius = 1 unit, and outer
# hollow cylinder with an inner radius of 2. In other words, the gap between
# them is 1 radial unit in length.
#
# The conductivity of both cylinders is set very large to achieve a uniform
# temperature in each cylinder. The temperature of the center node of the
# inner cylinder is ramped from 100 to 200 over one time unit. The temperature
# of the outside of the outer, hollow cylinder is held fixed at 100.
#
# A simple analytical solution is possible for the integrated heat flux
# between the inner and outer cylinders:
#
# Integrated Flux = (T_left - T_right) * (gapK/(r*ln(r2/r1))) * Area
#
# For gapK = 1 (default value)
#
# The area is taken as the area of the slave (inner) surface:
#
# Area = 2 * pi * h * r, where h is the height of the cylinder.
#
# The integrated heat flux across the gap at time 1 is then:
#
# 2*pi*h*k*delta_T/(ln(r2/r1))
# 2*pi*1*1*100/(ln(2/1)) = 906.5 watts
#
# For comparison, see results from the integrated flux post processors.
# This simulation makes use of symmetry, so only 1/4 of the cylinders is meshed
# As such, the integrated flux from the post processors is 1/4 of the total,
# or 226.6 watts.
# The value coming from the post processor is slightly less than this
# but converges as mesh refinement increases.
#
# Simulating contact is challenging. Regression tests that exercise
# contact features can be difficult to solve consistently across multiple
# platforms. While designing these tests, we felt it worth while to note
# some aspects of these tests. The following applies to:
# sphere3D.i, sphere2DRZ.i, cyl2D.i, and cyl3D.i.
# 1. We decided that to perform consistently across multiple platforms we
# would use very small convergence tolerance. In this test we chose an
# nl_rel_tol of 1e-12.
# 2. Due to such a high value for thermal conductivity (used here so that the
# domains come to a uniform temperature) the integrated flux at time = 0
# was relatively large (the value coming from SideIntegralFlux =
# -_diffusion_coef[_qp]*_grad_u[_qp]*_normals[_qp] where the diffusion coefficient
# here is thermal conductivity).
# Even though _grad_u[_qp] is small, in this case the diffusion coefficient
# is large. The result is a number that isn't exactly zero and tends to
# fail exodiff. For this reason the parameter execute_on = initial should not
# be used. That parameter is left to default settings in these regression tests.

# 1x1x1 unit cube with constant displacement on top face
#
# This problem was taken from "Finite element three-dimensional elastic-plastic
# creep analysis" by A. Levy, Eng. Struct., 1981, Vol. 3, January, pp. 9-16.
#
# The problem is a one-dimensional creep analysis. The top face is displaced 0.01
# units and held there. The stress relaxes in time according to the creep law.
#
# The analytic solution to this problem is (contrary to what is shown in the paper):
#
# / (E*ef)^3 \^(1/3)
# stress_yy = |--------------------|
# \ 3*a*E^4*ef^3*t + 1 /
#
# where E = 2.0e11 (Young's modulus)
# a = 3e-26 (creep coefficient)
# ef = 0.01 (displacement)
# t = 2160.0 (time)
#
# such that the analytical solution is computed to be 2.9518e3 Pa
#
# Averaged over the single element block, MOOSE calculates the stress in the yy direction to be
# to be 3.046e3 Pa, which is a 3.2% error from the analytical solution.

# This is a basic test of the system for continuum damage mechanics
# materials. It uses ScalarMaterialDamage for the damage model,
# which simply gets its damage index from another material. In this
# case, we prescribe the evolution of the damage index using a
# function. A single element has a fixed prescribed displacement
# on one side that puts the element in tension, and then the
# damage index evolves from 0 to 1 over time, and this verifies
# that the stress correspondingly drops to 0.

# The test is for an 1-D bar element of length 4m fixed on one end
# with a sinusoidal pulse dirichlet boundary condition applied to the other end.
# alpha, beta and gamma are Newmark time integration parameters
# The equation of motion in terms of matrices is:
#
# M*accel + K*((1+alpha)*disp-alpha*disp_old) = 0
#
# Here M is the mass matrix, K is the stiffness matrix
#
# The displacement at the second, third and fourth node at t = 0.1 are

# Pressure Test
#
# This test is designed to compute pressure loads on three faces of a unit cube.
# The pressure is computed as an auxiliary variable. It should give the same result
# as pressure_test.i
#
# The mesh is composed of one block with a single element. Symmetry bcs are
# applied to the faces opposite the pressures. Poisson's ratio is zero,
# which makes it trivial to check displacements.

# Mandel's problem of consolodation of a drained medium
# Using the FullySaturatedDarcyBase and FullySaturatedFullySaturatedMassTimeDerivative kernels
# with multiply_by_density = false, so that this problem becomes linear
# Note the use of consistent_with_displaced_mesh = false in the calculation of volumetric strain
#
# A sample is in plane strain.
# -a <= x <= a
# -b <= y <= b
# It is squashed with constant force by impermeable, frictionless plattens on its top and bottom surfaces (at y=+/-b)
# Fluid is allowed to leak out from its sides (at x=+/-a)
# The porepressure within the sample is monitored.
#
# As is common in the literature, this is simulated by
# considering the quarter-sample, 0<=x<=a and 0<=y<=b, with
# impermeable, roller BCs at x=0 and y=0 and y=b.
# Porepressure is fixed at zero on x=a.
# Porepressure and displacement are initialised to zero.
# Then the top (y=b) is moved downwards with prescribed velocity,
# so that the total force that is inducing this downwards velocity
# is fixed. The velocity is worked out by solving Mandel's problem
# analytically, and the total force is monitored in the simulation
# to check that it indeed remains constant.
#
# Here are the problem's parameters, and their values:
# Soil width. a = 1
# Soil height. b = 0.1
# Soil's Lame lambda. la = 0.5
# Soil's Lame mu, which is also the Soil's shear modulus. mu = G = 0.75
# Soil bulk modulus. K = la + 2*mu/3 = 1
# Drained Poisson ratio. nu = (3K - 2G)/(6K + 2G) = 0.2
# Soil bulk compliance. 1/K = 1
# Fluid bulk modulus. Kf = 8
# Fluid bulk compliance. 1/Kf = 0.125
# Soil initial porosity. phi0 = 0.1
# Biot coefficient. alpha = 0.6
# Biot modulus. M = 1/(phi0/Kf + (alpha - phi0)(1 - alpha)/K) = 4.705882
# Undrained bulk modulus. Ku = K + alpha^2*M = 2.694118
# Undrained Poisson ratio. nuu = (3Ku - 2G)/(6Ku + 2G) = 0.372627
# Skempton coefficient. B = alpha*M/Ku = 1.048035
# Fluid mobility (soil permeability/fluid viscosity). k = 1.5
# Consolidation coefficient. c = 2*k*B^2*G*(1-nu)*(1+nuu)^2/9/(1-nuu)/(nuu-nu) = 3.821656
# Normal stress on top. F = 1
#
# The solution for porepressure and displacements is given in
# AHD Cheng and E Detournay "A direct boundary element method for plane strain poroelasticity" International Journal of Numerical and Analytical Methods in Geomechanics 12 (1988) 551-572.
# The solution involves complicated infinite series, so I shall not write it here

#
# This test evaluates the capability of HeatConductionMaterial to define
# thermal conductivity as a function of temperature. The test uses the patch test
# cube mesh with a flux bc on one side and a temperature bc on the opposite side.
# The temperature bc changes as a function of time from 100 to 200. The thermal
# conductivity is a function of temperature, with k = 1 for temps = 100-199, k = 2
# for temps _>_ 200. The flux, q = 10 is constant. The Transient Executioner is used here
# although the interial kernel is omitted, so this is really a series of two steady-state
# solutions.

# This test covers the usage of the VariableTimeIntegrationAux
# kernel. Here we test three different schemes for integrating a field
# variable in time. Midpoint, Trapezoidal, and Simpson's rule are
# used. For this test, we use a manufactured solution and we compare
# the Trapezoidal and Simpson's rule, which must be exact for this
# exact solution, which is a linear function of time.
#
# The set up problem is
#
# du/dt - Laplacian(u) = Q
#
# with exact solution: u = t*(x*x+y*y).

# Test for rayleigh damping implemented using HHT time integration
#
# The test is for an 1D bar element of unit length fixed on one end
# with a ramped pressure boundary condition applied to the other end.
# zeta and eta correspond to the stiffness and mass proportional rayleigh damping
# alpha, beta and gamma are HHT time integration parameters
# The equation of motion in terms of matrices is:
#
# M*accel + (eta*M+zeta*K)*[(1+alpha)vel-alpha vel_old]
# + alpha*(K*disp - K*disp_old) + K*disp = P(t+alpha dt)*Area
#
# Here M is the mass matrix, K is the stiffness matrix, P is the applied pressure
#
# This equation is equivalent to:
#
# density*accel + eta*density*[(1+alpha)vel-alpha vel_old]
# + zeta*[(1+alpha)*d/dt(Div stress)- alpha*d/dt(Div stress_old)]
# + alpha *(Div stress - Div stress_old) +Div Stress= P(t+alpha dt)
#
# The first two terms on the left are evaluated using the Inertial force kernel
# The next three terms on the left involving zeta and alpha are evaluated using
# the DynamicStressDivergenceTensors Kernel
# The residual due to Pressure is evaluated using Pressure boundary condition
#
# The system will come to steady state slowly after the pressure becomes constant.
# Alpha equal to zero will result in Newmark integration.

# Area (A) = 1.0
# Iy = Iz = 0.16

# large rotations + small strain = -0.92 m in x and 2.38 m in y

# This test checks that hoop stress is calculated correctly for three orientations.
# 1. A hoop centered at (20,20,20) with vector (0,0,1)
# 2. A hoop centered at (-25,20,20) with vector (0,1,0)
# 3. A hoop centered at (-20,-20,20) with vector (1,0,0)
# All three have radius = 20, t = 1.

# Element mass tests
# This series of tests is designed to compute the mass of elements based on
# an evolving mass density calculation. The tests consist of expansion and compression
# of the elastic patch test model along each axis, uniform expansion and compression,
# and shear in each direction. The expansion and compression tests change the volume of
# the elements. The corresponding change in density should compensate for this so the
# mass remains constant. The shear tests should not result in a volume change, and this
# is checked too. The mass calculation is done with the post processor called Mass.
# The tests/file names are as follows:

# Mandel's problem of consolodation of a drained medium
#
# A sample is in plane strain.
# -a <= x <= a
# -b <= y <= b
# It is squashed with constant force by impermeable, frictionless plattens on its top and bottom surfaces (at y=+/-b)
# Fluid is allowed to leak out from its sides (at x=+/-a)
# The porepressure within the sample is monitored.
#
# As is common in the literature, this is simulated by
# considering the quarter-sample, 0<=x<=a and 0<=y<=b, with
# impermeable, roller BCs at x=0 and y=0 and y=b.
# Porepressure is fixed at zero on x=a.
# Porepressure and displacement are initialised to zero.
# Then the top (y=b) is moved downwards with prescribed velocity,
# so that the total force that is inducing this downwards velocity
# is fixed. The velocity is worked out by solving Mandel's problem
# analytically, and the total force is monitored in the simulation
# to check that it indeed remains constant.
#
# Here are the problem's parameters, and their values:
# Soil width. a = 1
# Soil height. b = 0.1
# Soil's Lame lambda. la = 0.5
# Soil's Lame mu, which is also the Soil's shear modulus. mu = G = 0.75
# Soil bulk modulus. K = la + 2*mu/3 = 1
# Drained Poisson ratio. nu = (3K - 2G)/(6K + 2G) = 0.2
# Soil bulk compliance. 1/K = 1
# Fluid bulk modulus. Kf = 8
# Fluid bulk compliance. 1/Kf = 0.125
# Soil initial porosity. phi0 = 0.1
# Biot coefficient. alpha = 0.6
# Biot modulus. M = 1/(phi0/Kf + (alpha - phi0)(1 - alpha)/K) = 4.705882
# Undrained bulk modulus. Ku = K + alpha^2*M = 2.694118
# Undrained Poisson ratio. nuu = (3Ku - 2G)/(6Ku + 2G) = 0.372627
# Skempton coefficient. B = alpha*M/Ku = 1.048035
# Fluid mobility (soil permeability/fluid viscosity). k = 1.5
# Consolidation coefficient. c = 2*k*B^2*G*(1-nu)*(1+nuu)^2/9/(1-nuu)/(nuu-nu) = 3.821656
# Normal stress on top. F = 1
#
# The solution for porepressure and displacements is given in
# AHD Cheng and E Detournay "A direct boundary element method for plane strain poroelasticity" International Journal of Numerical and Analytical Methods in Geomechanics 12 (1988) 551-572.
# The solution involves complicated infinite series, so I shall not write it here

# This tests the capability of the code to read input files in csv or space separated format.
# There are four variables and four functions of the same name; a,b,c, and d. The diffusion equation is "solved"
# for each of these variables with a boundary condition of type FunctionDirchletBC applied to a boundary
# (i.e. node set) that includes every node in the element, so the solution is the boundary condition defined by the function.
# Each boundary condition uses a function of type PiecewiseLinear that gets its value from a file,
# which could be in comma separated or space separated format. The input file can also contain comments.
#
# The files could have the form
# 0,1,2,3 # time
# 0,4,5,6 # bc value
# for format = row
# or
# 0,0
# 1,4
# 2,5
# 3,6
# for format = column
# Values in files could be separated by white space. See the .csv and .dat files for format examples.
#
# The value of the variables should correspond to the function.
# At time = 0, the variable = 0, at time = 1, variable = 4 and so on.

#
# This test is Example 3 from "A Consistent Formulation for the Integration
# of Combined Plasticity and Creep" by P. Duxbury, et al., Int J Numerical
# Methods in Engineering, Vol. 37, pp. 1277-1295, 1994.
#
# The problem is a one-dimensional bar which is loaded from yield to a value of twice
# the initial yield stress and then unloaded to return to the original stress. The
# bar must harden to the required yield stress during the load ramp, with no
# further yielding during unloading. The initial yield stress (sigma_0) is prescribed
# as 20 with a plastic strain hardening of 100. The mesh is a 1x1x1 cube with symmetry
# boundary conditions on three planes to provide a uniaxial stress field.
# The temperature is held constant at 1000.
#
# In the PowerLawCreep model, the creep strain rate is defined by:
#
# edot = A(sigma)**n * exp(-Q/(RT)) * t**m
#
# The creep law specified in the paper, however, defines the creep strain rate as:
#
# edot = Ao * mo * (sigma)**n * t**(mo-1)
# with the creep parameters given by
# Ao = 1e-7
# mo = 0.5
# n = 5
#
# thus, input parameters for the test were specified as:
# A = Ao * mo = 1e-7 * 0.5 = 0.5e-7
# m = mo-1 = -0.5
# n = 5
# Q = 0
#
# The variation of load P with time is:
# P = 20 + 20t 0 < t < 1
# P = 40 - 40(t-1) 1 < t 1.5
#
# The analytic solution for total strain during the loading period 0 < t < 1 is:
#
# e_tot = (sigma_0 + 20*t)/E + 0.2*t + A * t**0.5 * sigma_0**n * [ 1 + (5/3)*t +
# + 2*t**2 + (10/7)*t**3 + (5/9)**t**4 + (1/11)*t**5 }
#
# and during the unloading period 1 < t < 1.5:
#
# e_tot = (sigma_1 - 40*(t-1))/E + 0.2 + (4672/693) * A * sigma_0**n +
# A * sigma_0**n * [ t**0.5 * ( 32 - (80/3)*t + 16*t**2 - (40/7)*t**3
# + (10/9)*t**4 - (1/11)*t**5 ) - (11531/693) ]
#
# where sigma_1 is the stress at time t = 1.
#
# Assuming a Young's modulus (E) of 1000 and using the parameters defined above:
#
# e_tot(1) = 2.39734
# e_tot(1.5) = 3.16813
#
#
# The numerically computed solution is:
#
# e_tot(1) = 2.39826 (~0.04% error)
# e_tot(1.5) = 3.15663 (~0.36% error)

# The test is for an 1D bar element of length 4m fixed on one end

# Test for small strain euler beam vibration in y direction
# An impulse load is applied at the end of a cantilever beam of length 4m.
# The beam is massless with a lumped mass at the end of the beam. The lumped
# mass also has a moment of inertia associated with it.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# mass (m) = 0.01899772
# Moment of inertia of lumped mass:
# Ixx = 0.2
# Iyy = 0.1
# Izz = 0.1
# mass proportional damping coefficient (eta) = 0.1
# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the beam behaves like a Euler-Bernoulli beam.
# The displacement time history from this analysis matches with that obtained from Abaqus.
# Values from the first few time steps are as follows:
# time disp_y vel_y accel_y
# 0.0 0.0 0.0 0.0
# 0.1 0.001278249649738 0.025564992994761 0.51129985989521

# The test is for an 1D bar element of length 4m fixed on one end
# with a sinusoidal pulse dirichlet boundary condition applied to the other end.
# alpha, beta and gamma are HHT time integration parameters
# eta and zeta are mass dependent and stiffness dependent Rayleigh damping
# coefficients, respectively.
# The equation of motion in terms of matrices is:

# M*accel + (eta*M+zeta*K)*((1+alpha)*vel-alpha*vel_old)
# +(1+alpha)*K*disp-alpha*K*disp_old = 0
#
# Here M is the mass matrix, K is the stiffness matrix

#
# This is a test of the piece-wise linear strain hardening model using the
# small strain formulation. This test exercises the temperature-dependent
# hardening curve capability.
#
# Test procedure:
# 1. The element is pulled to and then beyond the yield stress for a given
# temperature.
# 2. The displacement is then constant while the temperature increases and
# the yield stress decreases. This results in a lower stress with more
# plastic strain.
# 3. The temperature decreases beyond its original value giving a higher
# yield stress. The displacement increases, causing increases stress to
# the new yield stress.
# 4. The temperature and yield stress are constant with increasing
# displacement giving a constant stress and more plastic strain.
#
# Plotting total_strain_yy on the x axis and stress_yy on the y axis shows
# the stress history in a clear way.

# Internal Volume Test
#
# This test is designed to compute the internal volume of a space considering
# an embedded volume inside.
#
# The mesh is composed of one block (1) with an interior cavity of volume 8.
# Block 2 sits in the cavity and has a volume of 1. Thus, the total volume
# is 7.
#
# The internal volume is then adjusted by a piecewise linear time varying
# function. Thus, the total volume is 7 plus the addition at the particular
# time.

# One 3D element under ramped displacement loading.
#
# loading in z direction:
# time : 0.0 0.1 0.2 0.3
# disp : 0.0 0.0 -0.01 -0.01
# Gravity is applied in y direction. To equilibrate the system
# under gravity, a static analysis is run in the first time step
# by turning off the inertial terms. (see controls block and
# DynamicTensorMechanics block).
# Result: The displacement at the top node in the z direction should match
# the prescribed displacement. Also, the z acceleration should
# be two triangular pulses, one peaking at 0.1 and another peaking at
# 0.2.
# The y displacement would be offset by the gravity displacement.
# Also the y acceleration and velocity should be zero until the loading in
# the z direction starts (i.e, until 0.1s)
# Note: The time step used in the displacement data file should match
# the simulation time step (dt and dtmin in the Executioner block).

# Test for rayleigh damping implemented using Newmark time integration
# The test is for an 1D bar element of unit length fixed on one end
# with a ramped pressure boundary condition applied to the other end.
# zeta and eta correspond to the stiffness and mass proportional rayleigh damping
# beta and gamma are Newmark time integration parameters
# The equation of motion in terms of matrices is:
#
# M*accel + eta*M*vel + zeta*K*vel + K*disp = P*Area
#
# Here M is the mass matrix, K is the stiffness matrix, P is the applied pressure
#
# This equation is equivalent to:
#
# density*accel + eta*density*vel + zeta*d/dt(Div stress) + Div stress = P
#
# The first two terms on the left are evaluated using the Inertial force kernel
# The next two terms on the left involving zeta are evaluated using the
# DynamicStressDivergenceTensors Kernel
# The residual due to Pressure is evaluated using Pressure boundary condition
#
# The system will come to steady state slowly after the pressure becomes constant.

# Patch Test
# This test is designed to compute constant xx, yy, zz, xy, yz, and xz
# stress on a set of irregular hexes. The mesh is composed of one
# block with seven elements. The elements form a unit cube with one
# internal element. There is a nodeset for each exterior node.
# The cube is displaced by 1e-6 units in x, 2e-6 in y, and 3e-6 in z.
# The faces are sheared as well (1e-6, 2e-6, and 3e-6 for xy, yz, and
# zx). This gives a uniform strain/stress state for all six unique
# tensor components. This displacement is again applied in the second
# step.
# With Young's modulus at 1e6 and Poisson's ratio at 0, the shear
# modulus is 5e5 (G=E/2/(1+nu)). Therefore, for the mechanical strain,
#
# stress xx = 1e6 * 1e-6 = 1
# stress yy = 1e6 * 2e-6 = 2
# stress zz = 1e6 * 3e-6 = 3
# stress xy = 2 * 5e5 * 1e-6 / 2 = 0.5
# (2 * G * gamma_xy / 2 = 2 * G * epsilon_xy)
# stress yz = 2 * 5e5 * 2e-6 / 2 = 1
# stress zx = 2 * 5e5 * 3e-6 / 2 = 1.5
# Young's modulus is a function of temperature for this test. The
# temperature changes from 100 to 500. The Young's modulus drops
# due to that temperature change from 1e6 to 6e5.
# Poisson's ratio also is a function of temperature and changes from
# 0 to 0.25.
# At the end of the temperature ramp, E=6e5 and nu=0.25. This gives
# G=2.4e=5. lambda=E*nu/(1+nu)/(1-2*nu)=2.4E5. The final stress
# is therefore
# stress xx = 2.4e5 * 12e-6 + 2*2.4e5*2e-6 = 3.84
# stress yy = 2.4e5 * 12e-6 + 2*2.4e5*4e-6 = 4.80
# stress zz = 2.4e5 * 12e-6 + 2*2.4e5*6e-6 = 5.76
# stress xy = 2 * 2.4e5 * 2e-6 / 2 = 0.48
# (2 * G * gamma_xy / 2 = 2 * G * epsilon_xy)
# stress yz = 2 * 2.4e5 * 4e-6 / 2 = 0.96
# stress xz = 2 * 2.4e5 * 6e-6 / 2 = 1.44

# Test for small strain euler beam vibration in y direction
# An impulse load is applied at the end of a cantilever beam of length 4m.
# The beam is massless with a lumped mass at the end of the beam. The lumped
# mass also has a moment of inertia associated with it.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# mass (m) = 0.01899772
# Moment of inertia of lumped mass:
# Ixx = 0.2
# Iyy = 0.1
# Izz = 0.1
# mass proportional damping coefficient (eta) = 0.1
# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the beam behaves like a Euler-Bernoulli beam.
# The displacement time history from this analysis matches with that obtained from Abaqus.
# Values from the first few time steps are as follows:

# This tests the thermal expansion coefficient function using both
# options to specify that function: mean and instantaneous. There
# two blocks, each containing a single element, and these use the
# two variants of the function.
# In this test, the instantaneous CTE function has a constant value,
# while the mean CTE function is an analytic function designed to
# give the same response. If \bar{alpha}(T) is the mean CTE function,
# and \alpha(T) is the instantaneous CTE function,
# \bar{\alpha}(T) = 1/(T-Tref) \intA^{T}_{Tsf} \alpha(T) dT
# where Tref is the reference temperature used to define the mean CTE
# function, and Tsf is the stress-free temperature.
# This version of the test uses finite deformation theory.
# The two models produce very similar results. There are slight
# differences due to the large deformation treatment.

#
# This test is Example 2 from "A Consistent Formulation for the Integration
# of Combined Plasticity and Creep" by P. Duxbury, et al., Int J Numerical
# Methods in Engineering, Vol. 37, pp. 1277-1295, 1994.
#
# The problem is a one-dimensional bar which is loaded from yield to a value of twice
# the initial yield stress and then unloaded to return to the original stress. The
# bar must harden to the required yield stress during the load ramp, with no
# further yielding during unloading. The initial yield stress (sigma_0) is prescribed
# as 20 with a plastic strain hardening of 100. The mesh is a 1x1x1 cube with symmetry
# boundary conditions on three planes to provide a uniaxial stress field.
#
# In the PowerLawCreep model, the creep strain rate is defined by:
#
# edot = A(sigma)**n * exp(-Q/(RT)) * t**m
#
# The creep law specified in the paper, however, defines the creep strain rate as:
#
# edot = Ao * mo * (sigma)**n * t**(mo-1)
# with the creep parameters given by
# Ao = 1e-7
# mo = 0.5
# n = 5
#
# thus, input parameters for the test were specified as:
# A = Ao * mo = 1e-7 * 0.5 = 0.5e-7
# m = mo-1 = -0.5
# n = 5
# Q = 0
#
# The variation of load P with time is:
# P = 20 + 20t 0 < t < 1
# P = 40 - 40(t-1) 1 < t 1.5
#
# The analytic solution for total strain during the loading period 0 < t < 1 is:
#
# e_tot = (sigma_0 + 20*t)/E + 0.2*t + A * t**0.5 * sigma_0**n * [ 1 + (5/3)*t +
# + 2*t**2 + (10/7)*t**3 + (5/9)**t**4 + (1/11)*t**5 ]
#
# and during the unloading period 1 < t < 1.5:
#
# e_tot = (sigma_1 - 40*(t-1))/E + 0.2 + (4672/693) * A * sigma_0**n +
# A * sigma_0**n * [ t**0.5 * ( 32 - (80/3)*t + 16*t**2 - (40/7)*t**3
# + (10/9)*t**4 - (1/11)*t**5 ) - (11531/693) ]
#
# where sigma_1 is the stress at time t = 1.
#
# Assuming a Young's modulus (E) of 1000 and using the parameters defined above:
#
# e_tot(1) = 2.39734
# e_tot(1.5) = 3.16813
#
#
# The numerically computed solution is:
#
# e_tot(1) = 2.39718 (~0.006% error)
# e_tot(1.5) = 3.15555 (~0.40% error)

# Test for small strain euler beam vibration in y direction
# The velocity and acceleration AuxVariables and the corresponding AuxKernels
# are set up using the LineElementAction using add_dynamic_variables. The action
# also creates the displacement variables, stress divergence kernels and
# beam strain. NodalTranslationalInertia is not created by the action.
# An impulse load is applied at the end of a cantilever beam of length 4m.
# The beam is massless with a lumped mass at the end of the beam
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# mass (m) = 0.01899772
# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the beam behaves like a Euler-Bernoulli beam.
# The theoretical first frequency of this beam is:
# f1 = 1/(2 pi) * sqrt(3EI/(mL^3)) = 0.25
# This implies that the corresponding time period of this beam is 4s.
# The FEM solution for this beam with 10 element gives time periods of 4s with time step of 0.01s.
# A higher time step of 0.1 s is used in the test to reduce computational time.
# The time history from this analysis matches with that obtained from Abaqus.
# Values from the first few time steps are as follows:
# time disp_y vel_y accel_y
# 0.0 0.0 0.0 0.0

# This is a basic test of the system for continuum damage mechanics
# materials. It uses ScalarMaterialDamage for the damage model,
# which simply gets its damage index from another material. In this
# case, we prescribe the evolution of the damage index using a
# function. A single element has a fixed prescribed displacement
# on one side that puts the element in tension, and then the
# damage index evolves from 0 to 1 over time, and this verifies
# that the stress correspondingly drops to 0.

modules/tensor_mechanics/test/tests/combined_creep_plasticity/combined_stress_relaxation.i
#
# 1x1x1 unit cube with constant displacement on top face
#
# This problem was taken from "Finite element three-dimensional elastic-plastic
# creep analysis" by A. Levy, Eng. Struct., 1981, Vol. 3, January, pp. 9-16.
#
# The problem is a one-dimensional creep analysis. The top face is displaced 0.01
# units and held there. The stress relaxes in time according to the creep law.
#
# The analytic solution to this problem is (contrary to what is shown in the paper):
#
# / (E*ef)^3 \^(1/3)
# stress_yy = |---------------------|
# \ 3*a*E^4*ef^3*t + 1 /
#
# where E = 2.0e11 (Young's modulus)
# a = 3e-26 (creep coefficient)
# ef = 0.01 (displacement)
# t = 2160.0 (time)
#
# such that the analytical solution is computed to be 2.9518e3 Pa
#
# Averaged over the single element block, MOOSE calculates the stress in the yy direction to be
# to be 3.046e3 Pa, which is a 3.2% error from the analytical solution.

# This simulation uses the piece-wise linear strain hardening model
# with the incremental small strain formulation; incremental small strain
# is required to produce the strain_increment for the DiscreteRadialReturnStressIncrement
# class, which handles the calculation of the stress increment to return
# to the yield surface in a J2 (isotropic) plasticity problem.
#
# This test is used to check the error messages in the discrete radial return
# model DiscreteRRIsotropicPlasticity; cli_args are used to check all of the
# error messages in the DiscreteRRIsotropicPlasticity model.

#
# This test is Example 3 from "A Consistent Formulation for the Integration
# of Combined Plasticity and Creep" by P. Duxbury, et al., Int J Numerical
# Methods in Engineering, Vol. 37, pp. 1277-1295, 1994.
#
# The problem is a one-dimensional bar which is loaded from yield to a value of twice
# the initial yield stress and then unloaded to return to the original stress. The
# bar must harden to the required yield stress during the load ramp, with no
# further yielding during unloading. The initial yield stress (sigma_0) is prescribed
# as 20 with a plastic strain hardening of 100. The mesh is a 1x1x1 cube with symmetry
# boundary conditions on three planes to provide a uniaxial stress field.
# The temperature is held constant at 1000.
#
# In the PowerLawCreep model, the creep strain rate is defined by:
#
# edot = A(sigma)**n * exp(-Q/(RT)) * t**m
#
# The creep law specified in the paper, however, defines the creep strain rate as:
#
# edot = Ao * mo * (sigma)**n * t**(mo-1)
# with the creep parameters given by
# Ao = 1e-7
# mo = 0.5
# n = 5
#
# thus, input parameters for the test were specified as:
# A = Ao * mo = 1e-7 * 0.5 = 0.5e-7
# m = mo-1 = -0.5
# n = 5
# Q = 0
#
# The variation of load P with time is:
# P = 20 + 20t 0 < t < 1
# P = 40 - 40(t-1) 1 < t 1.5
#
# The analytic solution for total strain during the loading period 0 < t < 1 is:
#
# e_tot = (sigma_0 + 20*t)/E + 0.2*t + A * t**0.5 * sigma_0**n * [ 1 + (5/3)*t +
# + 2*t**2 + (10/7)*t**3 + (5/9)**t**4 + (1/11)*t**5 }
#
# and during the unloading period 1 < t < 1.5:
#
# e_tot = (sigma_1 - 40*(t-1))/E + 0.2 + (4672/693) * A * sigma_0**n +
# A * sigma_0**n * [ t**0.5 * ( 32 - (80/3)*t + 16*t**2 - (40/7)*t**3
# + (10/9)*t**4 - (1/11)*t**5 ) - (11531/693) ]
#
# where sigma_1 is the stress at time t = 1.
#
# Assuming a Young's modulus (E) of 1000 and using the parameters defined above:
#
# e_tot(1) = 2.39734
# e_tot(1.5) = 3.16813
#
#
# The numerically computed solution is:
#
# e_tot(1) = 2.39826 (~0.04% error)
# e_tot(1.5) = 3.15663 (~0.36% error)

#
# Cavity Pressure Test
#
# This test is designed to compute an internal pressure based on
# p = n * R * T / V
# where
# p is the pressure
# n is the amount of material in the volume (moles)
# R is the universal gas constant
# T is the temperature
# V is the volume
#
# The mesh is composed of one block (1) with an interior cavity of volume 8.
# Block 2 sits in the cavity and has a volume of 1. Thus, the total
# initial volume is 7.
# The test adjusts n, T, and V in the following way:
# n => n0 + alpha * t
# T => T0 + beta * t
# V => V0 + gamma * t
# with
# alpha = n0
# beta = T0 / 2
# gamma = - (0.003322259...) * V0
# T0 = 240.54443866068704
# V0 = 7
# n0 = f(p0)
# p0 = 100
# R = 8.314472 J * K^(-1) * mol^(-1)
#
# So, n0 = p0 * V0 / R / T0 = 100 * 7 / 8.314472 / 240.544439
# = 0.35
#
# The parameters combined at t = 1 gives p = 301.

#
# This test is Example 2 from "A Consistent Formulation for the Integration
# of Combined Plasticity and Creep" by P. Duxbury, et al., Int J Numerical
# Methods in Engineering, Vol. 37, pp. 1277-1295, 1994.
#
# The problem is a one-dimensional bar which is loaded from yield to a value of twice
# the initial yield stress and then unloaded to return to the original stress. The
# bar must harden to the required yield stress during the load ramp, with no
# further yielding during unloading. The initial yield stress (sigma_0) is prescribed
# as 20 with a plastic strain hardening of 100. The mesh is a 1x1x1 cube with symmetry
# boundary conditions on three planes to provide a uniaxial stress field.
#
# In the PowerLawCreep model, the creep strain rate is defined by:
#
# edot = A(sigma)**n * exp(-Q/(RT)) * t**m
#
# The creep law specified in the paper, however, defines the creep strain rate as:
#
# edot = Ao * mo * (sigma)**n * t**(mo-1)
# with the creep parameters given by
# Ao = 1e-7
# mo = 0.5
# n = 5
#
# thus, input parameters for the test were specified as:
# A = Ao * mo = 1e-7 * 0.5 = 0.5e-7
# m = mo-1 = -0.5
# n = 5
# Q = 0
#
# The variation of load P with time is:
# P = 20 + 20t 0 < t < 1
# P = 40 - 40(t-1) 1 < t 1.5
#
# The analytic solution for total strain during the loading period 0 < t < 1 is:
#
# e_tot = (sigma_0 + 20*t)/E + 0.2*t + A * t**0.5 * sigma_0**n * [ 1 + (5/3)*t +
# + 2*t**2 + (10/7)*t**3 + (5/9)**t**4 + (1/11)*t**5 ]
#
# and during the unloading period 1 < t < 1.5:
#
# e_tot = (sigma_1 - 40*(t-1))/E + 0.2 + (4672/693) * A * sigma_0**n +
# A * sigma_0**n * [ t**0.5 * ( 32 - (80/3)*t + 16*t**2 - (40/7)*t**3
# + (10/9)*t**4 - (1/11)*t**5 ) - (11531/693) ]
#
# where sigma_1 is the stress at time t = 1.
#
# Assuming a Young's modulus (E) of 1000 and using the parameters defined above:
#
# e_tot(1) = 2.39734
# e_tot(1.5) = 3.16813
#
#
# The numerically computed solution is:
#
# e_tot(1) = 2.39718 (~0.006% error)
# e_tot(1.5) = 3.15555 (~0.40% error)

# Internal Volume Test
#
# This test is designed to compute the internal volume of a space considering
# an embedded volume inside.
#
# The mesh is composed of one block (1) with an interior cavity of volume 8.
# Block 2 sits in the cavity and has a volume of 1. Thus, the total volume
# is 7.
#
# The internal volume is then adjusted by a piecewise linear time varying
# function. Thus, the total volume is 7 plus the addition at the particular
# time.
#
# Time | Addition | Total volume
# 0 | 0.0 | 7.0

# This tests the thermal expansion coefficient function using both

# two blocks, each containing a single element, and these use the
# two variants of the function.
# In this test, the instantaneous CTE function has a constant value,
# while the mean CTE function is an analytic function designed to
# give the same response. If \bar{alpha}(T) is the mean CTE function,
# and \alpha(T) is the instantaneous CTE function,
# \bar{\alpha}(T) = 1/(T-Tref) \intA^{T}_{Tsf} \alpha(T) dT
# where Tref is the reference temperature used to define the mean CTE
# function, and Tsf is the stress-free temperature.
# The two models produce very similar results. There are slight
# differences due to the large deformation treatment.

# Test for small strain euler beam vibration in y direction
# An impulse load is applied at the end of a cantilever beam of length 4m.
# The beam is massless with a lumped mass at the end of the beam. The lumped
# mass also has a moment of inertia associated with it.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# mass (m) = 0.01899772
# Moment of inertia of lumped mass:
# Ixx = 0.2
# Iyy = 0.1
# Izz = 0.1
# mass proportional damping coefficient (eta) = 0.1
# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the beam behaves like a Euler-Bernoulli beam.
# The displacement time history from this analysis matches with that obtained from Abaqus.
# Values from the first few time steps are as follows:
# time disp_y vel_y accel_y
# 0.0 0.0 0.0 0.0
# 0.1 0.001278249649738 0.025564992994761 0.51129985989521

# Test for small strain euler beam vibration in y direction
# An impulse load is applied at the end of a cantilever beam of length 4m.
# The beam is massless with a lumped masses at the ends of the beam.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# mass = 0.01899772 at the cantilever end
# mass = 2.0 at the fixed end (just for file testing purposes does not alter result)
# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the beam behaves like a Euler-Bernoulli beam.
# The theoretical first frequency of this beam is:
# f1 = 1/(2 pi) * sqrt(3EI/(mL^3)) = 0.25
# This implies that the corresponding time period of this beam is 4s.
# The FEM solution for this beam with 10 element gives time periods of 4s with time step of 0.01s.
# A higher time step of 0.1 s is used in the test to reduce computational time.
# The time history from this analysis matches with that obtained from Abaqus.
# Values from the first few time steps are as follows:
# time disp_y vel_y accel_y
# 0.0 0.0 0.0 0.0
# 0.1 0.0013076435060869 0.026152870121738 0.52305740243477

# Cavity Pressure Test (Volume input as a vector of postprocessors)
#
# This test is designed to compute an internal pressure based on
# p = n * R * T / V
# where
# p is the pressure
# n is the amount of material in the volume (moles)
# R is the universal gas constant
# T is the temperature
# V is the volume
#
# The mesh is composed of one block (1) with an interior cavity of volume 8.
# Block 2 sits in the cavity and has a volume of 1. Thus, the total
# initial volume is 7.
# The test adjusts n, T, and V in the following way:
# n => n0 + alpha * t
# T => T0 + beta * t
# V => V0 + gamma * t
# with
# alpha = n0
# beta = T0 / 2
# gamma = - (0.003322259...) * V0
# T0 = 240.54443866068704
# V0 = 7
# n0 = f(p0)
# p0 = 100
# R = 8.314472 J * K^(-1) * mol^(-1)
#
# So, n0 = p0 * V0 / R / T0 = 100 * 7 / 8.314472 / 240.544439
# = 0.35
#
# In this test the internal volume is calculated as the sum of two Postprocessors
# internalVolumeInterior and internalVolumeExterior. This sum equals the value
# reported by the internalVolume postprocessor.
#
# The parameters combined at t = 1 gives p = 301.

# Test for rayleigh damping implemented using Newmark time integration
# The test is for an 1D bar element of unit length fixed on one end
# with a ramped pressure boundary condition applied to the other end.
# zeta and eta correspond to the stiffness and mass proportional rayleigh damping
# beta and gamma are Newmark time integration parameters
# The equation of motion in terms of matrices is:
#
# M*accel + eta*M*vel + zeta*K*vel + K*disp = P*Area
#
# Here M is the mass matrix, K is the stiffness matrix, P is the applied pressure
#
# This equation is equivalent to:
#
# density*accel + eta*density*vel + zeta*d/dt(Div stress) + Div stress = P
#
# The first two terms on the left are evaluated using the Inertial force kernel
# The next two terms on the left involving zeta are evaluated using the
# DynamicStressDivergenceTensors Kernel
# The residual due to Pressure is evaluated using Pressure boundary condition
#
# The system will come to steady state slowly after the pressure becomes constant.

# Pressure Test
#
# This test is taken from the Abaqus verification manual:
# "1.3.4 Axisymmetric solid elements"
#
# The two lower nodes are not allowed to translate in the z direction.
# Step 1:
# Pressure of 1000 is applied on each face.
# Step 2:
# Step 1 load plus a pressure on the vertical faces that varies from
# 0 to 1000 from top to bottom.
#
# Solution:
# Step 1:
# Stress xx, yy, zz = -1000
# Stress xy = 0
# Step 2:
# Stress xx, zz = -1500
# Stress yy = -1000
# Stress xy = 0

#
# This test checks elastic stress calculations with mechanical and thermal
# strain using finite strain formulation. Young's modulus is 3600, and Poisson's ratio is 0.2.
# The axisymmetric, plane strain 1D mesh is pulled with displacement of 2e-3.
# Thus, the strain is [log(1+1e-3)=9.995e-4, 0, log(1+1e-3)=9.995e-4] (xx, yy, zz). This gives stress of
# [4.9975, 1.999, 4.9975]. After a temperature increase of 100 with alpha of
# 1e-6, the stress becomes [4.3975, 1.399, 4.3975].

# Test for small strain euler beam vibration in y direction
# An impulse load is applied at the end of a cantilever beam of length 4m.
# The beam is massless with a lumped mass at the end of the beam
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# mass (m) = 0.01899772
# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the beam behaves like a Euler-Bernoulli beam.
# The theoretical first frequency of this beam is:
# f1 = 1/(2 pi) * sqrt(3EI/(mL^3)) = 0.25
# This implies that the corresponding time period of this beam is 4s.
# The FEM solution for this beam with 10 element gives time periods of 4s with time step of 0.01s.
# A higher time step of 0.1 s is used in the test to reduce computational time.
# The time history from this analysis matches with that obtained from Abaqus.
# Values from the first few time steps are as follows:
# time disp_y vel_y accel_y
# 0.0 0.0 0.0 0.0

# Mandel's problem of consolodation of a drained medium
#
# A sample is in plane strain.
# -a <= x <= a
# -b <= y <= b
# It is squashed with constant force by impermeable, frictionless plattens on its top and bottom surfaces (at y=+/-b)
# Fluid is allowed to leak out from its sides (at x=+/-a)
# The porepressure within the sample is monitored.
#
# As is common in the literature, this is simulated by
# considering the quarter-sample, 0<=x<=a and 0<=y<=b, with
# impermeable, roller BCs at x=0 and y=0 and y=b.
# Porepressure is fixed at zero on x=a.
# Porepressure and displacement are initialised to zero.
# Then the top (y=b) is moved downwards with prescribed velocity,
# so that the total force that is inducing this downwards velocity
# is fixed. The velocity is worked out by solving Mandel's problem
# analytically, and the total force is monitored in the simulation
# to check that it indeed remains constant.
#
# Here are the problem's parameters, and their values:
# Soil width. a = 1
# Soil height. b = 0.1
# Soil's Lame lambda. la = 0.5
# Soil's Lame mu, which is also the Soil's shear modulus. mu = G = 0.75
# Soil bulk modulus. K = la + 2*mu/3 = 1
# Drained Poisson ratio. nu = (3K - 2G)/(6K + 2G) = 0.2
# Soil bulk compliance. 1/K = 1
# Fluid bulk modulus. Kf = 8
# Fluid bulk compliance. 1/Kf = 0.125
# Soil initial porosity. phi0 = 0.1
# Biot coefficient. alpha = 0.6
# Biot modulus. M = 1/(phi0/Kf + (alpha - phi0)(1 - alpha)/K) = 4.705882
# Undrained bulk modulus. Ku = K + alpha^2*M = 2.694118
# Undrained Poisson ratio. nuu = (3Ku - 2G)/(6Ku + 2G) = 0.372627
# Skempton coefficient. B = alpha*M/Ku = 1.048035
# Fluid mobility (soil permeability/fluid viscosity). k = 1.5
# Consolidation coefficient. c = 2*k*B^2*G*(1-nu)*(1+nuu)^2/9/(1-nuu)/(nuu-nu) = 3.821656
# Normal stress on top. F = 1
#
# The solution for porepressure and displacements is given in
# AHD Cheng and E Detournay "A direct boundary element method for plane strain poroelasticity" International Journal of Numerical and Analytical Methods in Geomechanics 12 (1988) 551-572.

# Patch Test
# This test is designed to compute constant xx, yy, zz, xy, yz, and xz
# stress on a set of irregular hexes. The mesh is composed of one
# block with seven elements. The elements form a unit cube with one
# internal element. There is a nodeset for each exterior node.
# The cube is displaced by 1e-6 units in x, 2e-6 in y, and 3e-6 in z.
# The faces are sheared as well (1e-6, 2e-6, and 3e-6 for xy, yz, and
# zx). This gives a uniform strain/stress state for all six unique
# tensor components. This displacement is again applied in the second
# step.
# With Young's modulus at 1e6 and Poisson's ratio at 0, the shear
# modulus is 5e5 (G=E/2/(1+nu)). Therefore, for the mechanical strain,
#
# stress xx = 1e6 * 1e-6 = 1
# stress yy = 1e6 * 2e-6 = 2
# stress zz = 1e6 * 3e-6 = 3
# stress xy = 2 * 5e5 * 1e-6 / 2 = 0.5
# (2 * G * gamma_xy / 2 = 2 * G * epsilon_xy)
# stress yz = 2 * 5e5 * 2e-6 / 2 = 1
# stress zx = 2 * 5e5 * 3e-6 / 2 = 1.5
# Young's modulus is a function of temperature for this test. The
# temperature changes from 100 to 500. The Young's modulus drops
# due to that temperature change from 1e6 to 6e5.
# Poisson's ratio also is a function of temperature and changes from
# 0 to 0.25.
# At the end of the temperature ramp, E=6e5 and nu=0.25. This gives
# G=2.4e=5. lambda=E*nu/(1+nu)/(1-2*nu)=2.4E5. The final stress
# is therefore
# stress xx = 2.4e5 * 12e-6 + 2*2.4e5*2e-6 = 3.84
# stress yy = 2.4e5 * 12e-6 + 2*2.4e5*4e-6 = 4.80
# stress zz = 2.4e5 * 12e-6 + 2*2.4e5*6e-6 = 5.76
# stress xy = 2 * 2.4e5 * 2e-6 / 2 = 0.48
# (2 * G * gamma_xy / 2 = 2 * G * epsilon_xy)
# stress yz = 2 * 2.4e5 * 4e-6 / 2 = 0.96
# stress xz = 2 * 2.4e5 * 6e-6 / 2 = 1.44

# Wave propogation in 1-D using HHT time integration in the presence
# of Rayleigh damping
#
# The test is for an 1-D bar element of length 4m fixed on one end
# with a sinusoidal pulse dirichlet boundary condition applied to the
# other end. alpha, beta and gamma are HHT time integration
# parameters eta and zeta are mass dependent and stiffness dependent
# Rayleigh damping coefficients, respectively. The equation of motion
# in terms of matrices is:
#
# M*accel + (eta*M+zeta*K)*((1+alpha)*vel-alpha*vel_old)+(1+alpha)*K*disp-alpha*K*disp_old = 0
#
# Here M is the mass matrix, K is the stiffness matrix
#
# The displacement at the first, second, third and fourth node at t = 0.1 are
# -7.787499960311491942e-02, 1.955566679096475483e-02 and -4.634888180231294501e-03, respectively.

#
# 2-D RZ Gap Heat Transfer Test without mechanics
#
# This test exercises 1-D gap heat transfer for a constant conductivity gap.
#
# The mesh consists of two element blocks containing one element each. Each
# element is a unit cube. They sit next to one another with a unit between them.
#
# The conductivity of both blocks is set very large to achieve a uniform temperature
# across each block. The temperature of the far left boundary
# is ramped from 100 to 200 over one time unit, and then held fixed for an additional
# time unit. The temperature of the far right boundary is held fixed at 100.
#
# A simple analytical solution is possible for the heat flux between the blocks, or cylinders in the case of RZ.:
#
# Flux = (T_left - T_right) * (gapK/(r*ln(r2/r1)))
#
# For gapK = 1 (default value)
#
# The integrated heat flux across the gap at time 2 is then:
#
# 2*pi*h*k*delta_T/(ln(r2/r1))
# 2*pi*1*1*100/(ln(2/1)) = 906.5 watts
#
# For comparison, see results from the flux post processors.
#
# As a second test, use the rectilinear (parallel plate) form of the gap heat transfer.
#
# Flux = (T_left - T_right) * (gapK/gapL)
#
# For gapK = 1 (default value)
#
# The integrated heat flux across the gap at time 2 is then:
#
# 2*pi*h*k*delta_T/(1)
# 2*pi*1*1*100/(1) = 628.3 watts
#
# For comparison, see results from the flux post processors.

# Test for small strain euler beam vibration in y direction
# An impulse load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# density (rho) = 1.0
# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the beam behaves like a Euler-Bernoulli beam.
# The theoretical first and third frequencies of this beam are:
# f1 = 1/(2 pi) * (3.5156/L^2) * sqrt(EI/rho)
# f2 = 6.268 f1
# This implies that the corresponding time period of this beam are 2.858 s and 0.455s
# The FEM solution for this beam with 10 element gives time periods of 2.856 s and 0.4505s with a time step of 0.01.
# A smaller time step is required to obtain a closer match for the lower time periods/higher frequencies.
# A higher time step of 0.05 is used in this test to reduce testing time.
# The time history from this analysis matches with that obtained from Abaqus.
# Values from the first few time steps are as follows:
# time disp_y vel_y accel_y
# 0 0.0 0.0 0.0

#
# This test checks elastic stress calculations with mechanical and thermal
# strain using incremental small strain formulation. Young's modulus is 3600, and Poisson's ratio is 0.2.
# The axisymmetric, plane strain 1D mesh is pulled with 1e-6 strain. Thus,
# the strain is [1e-6, 0, 1e-6] (xx, yy, zz). This gives stress of
# [5e-3, 2e-3, 5e-3]. After a temperature increase of 100 with alpha of
# 1e-8, the stress becomes [-1e-3, -4e-3, -1e-3].

# Test for small strain euler beam vibration in y direction
# An impulse load is applied at the end of a cantilever beam of length 5ft (60 in).
# The beam is massless with a lumped mass at the end of the beam of 5000 lb
# The properties of the cantilever beam are as follows:
# E = 1e7 and I = 120 in^4
# Assuming a square cross section A = sqrt(12 * I) = 37.95
# Shear modulus (G) = 3.846e6
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 1.0
# mass (m) = 5000 lb / 386 = 12.95
# The theoretical first frequency of this beam is:
# f1 = 1/(2 pi) * sqrt(3EI/(mL^3)) = 5.71 cps
# This implies that the corresponding time period of this beam is 0.175 s.
# The FEM solution for this beam with 10 elements gives
# a time period of 0.175 s with time step of 0.005 s.

# Truss in two dimensional space
#
# The truss is made of five equilateral triangles supported at each end.
# The truss starts at (0,0). At (1,0), there is a point load of 25.
# The reactions are therefore
# Ryleft = 2/3 * 25 = 16.7
# Ryright = 1/3 * 25 = 8.33
# The area of each member is 0.8.
# Statics gives the stress in each member. For example, for element 6 (from
# (0,0) to (1/2,sqrt(3)/2)), the force is
# f = 2/3 * 25 * 2/sqrt(3) = 100/3/sqrt(3) (compressive)
# and the stress is
# s = -100/3/sqrt(3)/0.8 = -24.06

#
# 2D Cylindrical Gap Heat Transfer Test.
#
# This test exercises 2D gap heat transfer for a constant conductivity gap.
#
# The mesh consists of an inner solid cylinder of radius = 1 unit, and outer
# hollow cylinder with an inner radius of 2 in the x-y plane. In other words,
# the gap between them is 1 radial unit in length.
#
# The conductivity of both cylinders is set very large to achieve a uniform
# temperature in each cylinder. The temperature of the center node of the
# inner cylinder is ramped from 100 to 200 over one time unit. The temperature
# of the outside of the outer, hollow cylinder is held fixed at 100.
#
# A simple analytical solution is possible for the integrated heat flux
# between the inner and outer cylinders:
#
# Integrated Flux = (T_left - T_right) * (gapK/(r*ln(r2/r1))) * Area
#
# For gapK = 1 (default value)
#
# The area is taken as the area of the slave (inner) surface:
#
# Area = 2 * pi * h * r, where h is the height of the cylinder.
#
# The integrated heat flux across the gap at time 1 is then:
#
# 2*pi*h*k*delta_T/(ln(r2/r1))
# 2*pi*1*1*100/(ln(2/1)) = 906.5 watts
#
# For comparison, see results from the integrated flux post processors.
# This simulation makes use of symmetry, so only 1/4 of the cylinders is meshed
# As such, the integrated flux from the post processors is 1/4 of the total,
# or 226.6 watts.
# The value coming from the post processor is slightly less than this
# but converges as mesh refinement increases.
# Note that the 2D and 3D results are the same.
#
# Simulating contact is challenging. Regression tests that exercise
# contact features can be difficult to solve consistently across multiple
# platforms. While designing these tests, we felt it worth while to note
# some aspects of these tests. The following applies to:
# sphere3D.i, sphere2DRZ.i, cyl2D.i, and cyl3D.i.
# 1. We decided that to perform consistently across multiple platforms we
# would use very small convergence tolerance. In this test we chose an
# nl_rel_tol of 1e-12.
# 2. Due to such a high value for thermal conductivity (used here so that the
# domains come to a uniform temperature) the integrated flux at time = 0
# was relatively large (the value coming from SideIntegralFlux =
# -_diffusion_coef[_qp]*_grad_u[_qp]*_normals[_qp] where the diffusion coefficient
# here is thermal conductivity).
# Even though _grad_u[_qp] is small, in this case the diffusion coefficient
# is large. The result is a number that isn't exactly zero and tends to
# fail exodiff. For this reason the parameter execute_on = initial should not
# be used. That parameter is left to default settings in these regression tests.
