Compute Finite Strain Elastic Stress
Compute stress using elasticity for finite strains
Description
This material, ComputeFiniteStrainElasticStress computes the elastic stress for an incremental formulation, both incremental small (ComputeIncrementalSmallStrain type) and incremental finite (ComputeFiniteStrain type) strain formulations. This stress class is compatible with both Cartesian and non-Cartesian strain calculators, including Axisymmetric and RSpherical.
Elastic materials do not experience permanent deformation, and all elastic strain and elastic stress is recoverable. Elastic stress is related to elastic strain through the elasticity tensor (1) where is the strain increment; this strain measure is also the sum of the mechanical elastic strain and any eigenstrains in the system.

# The stress solution is given as:
# xx = yy = zz = 19900
# xy = 0
#
# If strain = log(1+1e-2) = 0.00995033...
# then
# stress = E/(1+PR)/(1-2*PR)*(1-PR +PR +PR)*strain = 19900.6617

#
# The code computes stress = 19900.6617 when
# increment_calculation = eigen. There is a small error when the
# rashidapprox option is used.
#
# Since the strain is 1e-3 in all three directions, the new density should be

# This test involves only thermal expansion strains on a 2x2x2 cube of approximate
# steel material; however, in this case the stress free temperature of the material
# has been set to 200K so that there is an initial delta temperature of 100K.
# An initial temperature of 300K is given for the material,
# and an auxkernel is used to calculate the temperature in the entire cube to
# raise the temperature each time step. The final temperature is 675K
# The thermal strain increment should therefore be
# (675K - 300K) * 1.3e-5 1/K + 100K * 1.3e-5 1/K = 6.175e-3 m/m.
# This test uses a start up step to identify problems in the calculation of
# eigenstrains with a stress free temperature that is different from the initial
# value of the temperature in the problem

#
# 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.

#
# 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.

# This test involves only thermal expansion strains on a 2x2x2 cube of approximate
# steel material. An initial temperature of 25 degrees C is given for the material,
# and an auxkernel is used to calculate the temperature in the entire cube to
# raise the temperature each time step. After the first timestep,in which the
# temperature jumps, the temperature increases by 6.25C each timestep.
# The thermal strain increment should therefore be
# 6.25 C * 1.3e-5 1/C = 8.125e-5 m/m.

#
# 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.

# Rotation Test
#
# This test is designed to compute stress based on uniaxial strain
# and then follow that stress as the mesh is rotated 90 degrees.
#
# The mesh is composed of one block with a single element. The nodal
# displacements in the three directions are prescribed. Poisson's
# ratio is 1/3, and Young's modulus is 1e6.
#
# This test is mentioned in
# K. Kamojjala, R. Brannon, A. Sadeghirad, and J. Guilkey, "Verification
# tests in solid mechanics," Engineering with Computers, Vol. 31, 2015.

# The primary purpose of this test is to verify that the ability to combine
# multiple eigenstrains works correctly. It should behave identically to the
# constant_expansion_coeff.i model in the thermal_expansion directory. Instead
# of having the eigenstrain names passed directly to the TensorMechanics MasterAction,
# the MasterAction should be able to extract the necessary eigenstrains and apply
# to their respective blocks without reduncacy.
# This test involves only thermal expansion strains on a 2x2x2 cube of approximate
# steel material. An initial temperature of 25 degrees C is given for the material,
# and an auxkernel is used to calculate the temperature in the entire cube to
# raise the temperature each time step. After the first timestep,in which the
# temperature jumps, the temperature increases by 6.25C each timestep.
# The thermal strain increment should therefore be
# 6.25 C * 1.3e-5 1/C = 8.125e-5 m/m.

# Gravity Test
#
# This test is designed to exercise the gravity body force kernel.
#
# The mesh for this problem is a rectangular bar 10 units by 1 unit
# by 1 unit.
#
# The boundary conditions for this problem are as follows. The
# displacement is zero on each of side that faces a negative
# coordinate direction. The acceleration of gravity is 20.
#
# The material has a Young's modulus of 1e6 and a density of 2.
#
# The analytic solution for the displacement along the bar is:
#
# u(x) = -b*x^2/(2*E)+b*L*x/E
#
# The displacement at x=L is b*L^2/(2*E) = 2*20*10*10/(2*1e6) = 0.002.
#
# The analytic solution for the stress along the bar assuming linear
# elasticity is:
#
# S(x) = b*(L-x)
#
# The stress at x=0 is b*L = 2*20*10 = 400.
#
# Note: The simulation does not measure stress at x=0. The stress
# is reported at element centers. The element closest to x=0 sits
# at x = 1/4 and has a stress of 390. This matches the linear
# stress distribution that is expected. The same situation applies
# at x = L where the stress is zero analytically. The nearest
# element is at x=9.75 where the stress is 10.

# 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.

# 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

# Gravity Test
#
# This test is designed to exercise the gravity body force kernel.
#
# The mesh for this problem is a rectangular bar 10 units by 1 unit
# by 1 unit.
#
# The boundary conditions for this problem are as follows. The
# displacement is zero on each of side that faces a negative
# coordinate direction. The acceleration of gravity is 20.
#
# The material has a Young's modulus of 1e6 and a density of 2.
#
# The analytic solution for the displacement along the bar is:
#
# u(x) = -b*x^2/(2*E)+b*L*x/E
#
# The displacement at x=L is b*L^2/(2*E) = 2*20*10*10/(2*1e6) = 0.002.
#
# The analytic solution for the stress along the bar assuming linear
# elasticity is:
#
# S(x) = b*(L-x)
#
# The stress at x=0 is b*L = 2*20*10 = 400.
#
# Note: The simulation does not measure stress at x=0. The stress
# is reported at element centers. The element closest to x=0 sits
# at x = 1/4 and has a stress of 390. This matches the linear
# stress distribution that is expected. The same situation applies
# at x = L where the stress is zero analytically. The nearest
# element is at x=9.75 where the stress is 10.

# 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

# contact using the penalty method. In this test a sinusoidal
# displacement is applied in the horizontal direction to simulate
# a small block come in and out of contact as it slides down a larger block.
#
# The sinusoid is of the form 0.4sin(4t)+0.2 and a friction coefficient
# of 0.4 is used. The gold file is run on one processor and the benchmark
# case is run on a minimum of 4 processors to ensure no parallel variability
# in the contact pressure and penetration results. Further documentation can
# found in moose/modules/contact/doc/sliding_block/

# This problem is taken from the Abaqus verification manual:
# "1.5.4 Patch test for axisymmetric elements"
# The stress solution is given as:
# xx = yy = zz = 19900
# xy = 0
#
# If strain = log(1+1e-2) = 0.00995033...
# then
# stress = E/(1+PR)/(1-2*PR)*(1-PR +PR +PR)*strain = 19900.6617
# with E = 1e6 and PR = 0.25.
#
# The code computes stress = 19900.6617 when
# increment_calculation = eigen. There is a small error when the
# rashidapprox option is used.
#
# Since the strain is 1e-3 in all three directions, the new density should be
# new_density = original_density * V_0 / V
# new_density = 0.283 / (1 + 9.95e-3 + 9.95e-3 + 9,95e-3) = 0.2747973

#
# 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 is a benchmark test that checks constraint based frictional
# contact using the penalty method. In this test a sinusoidal
# displacement is applied in the horizontal direction to simulate
# a small block come in and out of contact as it slides down a larger block.
#
# The sinusoid is of the form 0.4sin(4t)+0.2 and a friction coefficient
# of 0.2 is used. The gold file is run on one processor and the benchmark
# case is run on a minimum of 4 processors to ensure no parallel variability
# in the contact pressure and penetration results. Further documentation can

# 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 involves only thermal expansion strains on a 2x2x2 cube of approximate
# steel material. An initial temperature of 25 degrees C is given for the material,
# and an auxkernel is used to calculate the temperature in the entire cube to
# raise the temperature each time step. After the first timestep,in which the
# temperature jumps, the temperature increases by 6.25C each timestep.
# The thermal strain increment should therefore be
# 6.25 C * 1.3e-5 1/C = 8.125e-5 m/m.
# This test is also designed to be used to identify problems with restart files

# Poroelastic response of a borehole.
#
# LOWRES VERSION: this version does not give perfect agreement with the analytical solution
#
# A fully-saturated medium contains a fluid with a homogeneous porepressure,
# but an anisitropic insitu stress. A infinitely-long borehole aligned with
# the $$z$$ axis is instanteously excavated. The borehole boundary is
# stress-free and allowed to freely drain. This problem is analysed using
# plane-strain conditions (no $$z$$ displacement).
#
# The solution in Laplace space is found in E Detournay and AHD Cheng "Poroelastic response of a borehole in a non-hydrostatic stress field". International Journal of Rock Mechanics and Mining Sciences and Geomechanics Abstracts 25 (1988) 171-182. In the small-time limit, the Laplace transforms may be performed. There is one typo in the paper. Equation (A4)'s final term should be -(a/r)\sqrt(4ct/(a^2\pi)), and not +(a/r)\sqrt(4ct/(a^2\pi)).
#
# Because realistic parameters are chosen (below),
# the residual for porepressure is much smaller than
# the residuals for the displacements. Therefore the
# scaling parameter is chosen. Also note that the
# insitu stresses are effective stresses, not total
# stresses, but the solution in the above paper is
# expressed in terms of total stresses.
#
# Here are the problem's parameters, and their values:
# Borehole radius. a = 1
# Rock's Lame lambda. la = 0.5E9
# Rock's Lame mu, which is also the Rock's shear modulus. mu = G = 1.5E9
# Rock bulk modulus. K = la + 2*mu/3 = 1.5E9
# Drained Poisson ratio. nu = (3K - 2G)/(6K + 2G) = 0.125
# Rock bulk compliance. 1/K = 0.66666666E-9
# Fluid bulk modulus. Kf = 0.7171315E9
# Fluid bulk compliance. 1/Kf = 1.39444444E-9
# Rock initial porosity. phi0 = 0.3
# Biot coefficient. alpha = 0.65
# Biot modulus. M = 1/(phi0/Kf + (alpha - phi0)(1 - alpha)/K) = 2E9
# Undrained bulk modulus. Ku = K + alpha^2*M = 2.345E9
# Undrained Poisson ratio. nuu = (3Ku - 2G)/(6Ku + 2G) = 0.2364
# Skempton coefficient. B = alpha*M/Ku = 0.554
# Fluid mobility (rock permeability/fluid viscosity). k = 1E-12

(modules/tensor_mechanics/test/tests/action/action_eigenstrain.i)
# The primary purpose of this test is to verify that the ability to combine
# multiple eigenstrains works correctly. It should behave identically to the
# constant_expansion_coeff.i model in the thermal_expansion directory. Instead
# of having the eigenstrain names passed directly to the TensorMechanics MasterAction,
# the MasterAction should be able to extract the necessary eigenstrains and apply
# to their respective blocks without reduncacy.
# This test involves only thermal expansion strains on a 2x2x2 cube of approximate
# steel material. An initial temperature of 25 degrees C is given for the material,
# and an auxkernel is used to calculate the temperature in the entire cube to
# raise the temperature each time step. After the first timestep,in which the
# temperature jumps, the temperature increases by 6.25C each timestep.
# The thermal strain increment should therefore be
# 6.25 C * 1.3e-5 1/C = 8.125e-5 m/m.

# Considers the mechanics solution for a thick spherical shell that is uniformly
# pressurized on the inner and outer surfaces, using 2D axisymmetric geometry.
# This test uses the strain calculator ComputeAxisymmetricRZFiniteStrain,
# which is generated through the use of the TensorMechanics MasterAction.
#
# From Roark (Formulas for Stress and Strain, McGraw-Hill, 1975), the radially-dependent
# circumferential stress in a uniformly pressurized thick spherical shell is given by:
#
# S(r) = [ Pi[ri^3(2r^3+ro^3)] - Po[ro^3(2r^3+ri^3)] ] / [2r^3(ro^3-ri^3)]
#
# where:
# Pi = inner pressure
# Po = outer pressure
# ri = inner radius
# ro = outer radius
#
# The tests assume an inner and outer radii of 5 and 10, with internal and external
# pressures of 100000 and 200000 at t = 1.0, respectively. The resulting compressive
# tangential stress is largest at the inner wall and, from the above equation, has a
# value of -271429.
#
# RESULTS are below. Since stresses are average element values, values for the
# edge element and one-element-in are used to extrapolate the stress to the
# inner surface. The vesrion of the tests that are checked use the coarsest meshes.
#

#
# Cavity Pressure Test
#
# This test is designed to compute an internal pressure based on
# p = n * R * / (V_cavity / T_cavity + V_add / T_add)
# where
# p is the pressure
# n is the amount of material in the volume (moles)
# R is the universal gas constant
# T_cavity is the temperature in the cavity
# T_add is the temperature of the additional 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. An additional volume of 2 is added.
#
# The test adjusts n, T, and V in the following way:
# n => n0 + alpha * t
# T => T0 + beta * t
# V => V_cavity0 + gamma * t + V_add
# with
# alpha = n0
# beta = T0 / 2
# gamma = -(0.003322259...) * V0
# T0 = 240.54443866068704
# V_cavity0 = 7
# V_add = 2
# T_add = 100
# n0 = f(p0)
# p0 = 100
# R = 8.314472 J * K^(-1) * mol^(-1)
#
# An additional volume of 2 with a temperature of 100.0 is included.
#
# So, n0 = p0 * (V_cavity / T_cavity + V_add / T_add) / R
# = 100 * (7 / 240.544439 + 2 / 100) / 8.314472
# = 0.59054
#
# The parameters combined at t = 1 gives p = 249.647.
#
# 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.

# 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

#
# 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].

# Considers the mechanics solution for a thick spherical shell that is uniformly
# pressurized on the inner and outer surfaces, using 3D geometry.
#
# From Roark (Formulas for Stress and Strain, McGraw-Hill, 1975), the radially-dependent
# circumferential stress in a uniformly pressurized thick spherical shell is given by:
#
# S(r) = [ Pi[ri^3(2r^3+ro^3)] - Po[ro^3(2r^3+ri^3)] ] / [2r^3(ro^3-ri^3)]
#
# where:
# Pi = inner pressure
# Po = outer pressure
# ri = inner radius
# ro = outer radius
#
# The tests assume an inner and outer radii of 5 and 10, with internal and external
# pressures of 100000 and 200000 at t = 1.0, respectively. The resulting compressive
# tangential stress is largest at the inner wall and, from the above equation, has a
# value of -271429.
#
# RESULTS are below. Since stresses are average element values, values for the
# edge element and one-element-in are used to extrapolate the stress to the
# inner surface. The vesrion of the tests that are checked use the coarsest meshes.
#

# Gravity Test
#
# This test is similar to the other gravity tests, but it also tests the
# capability in MaterialTensorAux to return the stress of a single,
# specified integration point, rather than the element average.
# To get the stress at a single integration point, set the parameter
# qp_select to the integration point number (i.e. 0-9 for a quad 8)
# in the AuxKernel
#
# The mesh for this problem is a unit square.
#
# The boundary conditions for this problem are as follows. The
# displacement is zero on each of side that faces a negative
# coordinate direction. The acceleration of gravity is 20.
#
# The material has a Young's modulus of 1e6 and a density of 2.
#
# The analytic solution for the displacement along the bar is:
#
# u(x) = -b*x^2/(2*E)+b*L*x/E
#
# The displacement at x=L is b*L^2/(2*E) = 2*20*1*1/(2*1e6) = 0.00002.
#
# The analytic solution for the stress along the bar assuming linear
# elasticity is:
#
# S(x) = b*(L-x)
#
# The stress at x=0 is b*L = 2*20*1 = 40.
#
# Note: The isoparametric coordinate for a quad8 (fourth order) element
# is: +/- 0.77459667 and 0. For a 1 unit square with the edge of
# the element in the x = 0 plane, there would be an integration point
# at x_coordinate 0.5 - 0.5*0.77459667 (0.11270167), 0.5, and
# 0.50 + 0.5*0.77459667 (0.88729834).
#
# The corresponding stresses are:
#
# S(0.11270167) = 40(1-0.11270167) = 35.491933
# S(0.5) = 40(1-0.5) = 20
# S(0.88729834) = 40(1-0.88729834) = 4.5080664
#
# These stresses are a precise match to the simulation result.

# Gravity Test
#
# This test is designed to exercise the gravity body force rz kernel.
#
# The mesh for this problem is a rectangle 10 units by 1 unit.
#
# The boundary conditions for this problem are as follows. The
# displacement is zero at the top. The acceleration of gravity is 20.
#
# The material has a Young's modulus of 1e6 and a density of 2.
#
# The analytic solution for the displacement along the bar is:
#
# u(y) = -b*y^2/(2*E)+b*L*y/E
#
# The displacement at y=L is b*L^2/(2*E) = 2*20*10*10/(2*1e6) = 0.002.
#
# The analytic solution for the stress along the bar assuming linear
# elasticity is:
#
# S(y) = b*(L-y)
#
# The stress at x=0 is b*L = 2*20*10 = 400.
#
# Note: The simulation does not measure stress at y=0. The stress
# is reported at element centers. The element closest to y=0 sits
# at y = 1/4 and has a stress of 390. This matches the linear
# stress distribution that is expected. The same situation applies
# at y = L where the stress is zero analytically. The nearest
# element is at y=9.75 where the stress is 10.

# In this test, the instantaneous CTE function has a constant value,

# This version of the test uses finite deformation theory.

# This simulation models the mechanics solution for a hollow sphere under
# pressure, applied on the outer surfaces, using 1D spherical symmetry
# assumpitions. The inner radius of the sphere, r = 4mm, is pinned to prevent
# rigid body movement of the sphere.
#
# From Bower (Applied Mechanics of Solids, 2008, available online at
# solidmechanics.org/text/Chapter4_1/Chapter4_1.htm), and applying the outer
# pressure and pinned displacement boundary conditions set in this simulation,
# the radial displacement is given by:
#
# u(r) = \frac{P(1 + v)(1 - 2v)b^3}{E(b^3(1 + v) + 2a^3(1-2v))} * (\frac{a^3}{r^2} - r)
#
# where P is the applied pressure, b is the outer radius, a is the inner radius,
# v is Poisson's ration, E is Young's Modulus, and r is the radial position.
#
# The radial stress is given by:
#
# S(r) = \frac{Pb^3}{b^3(1 + v) + 2a^3(1 - 2v)} * (\frac{2a^3}{r^3}(2v - 1) - (1 + v))
#
# The test assumes an inner radius of 4mm, and outer radius of 9 mm,
# zero displacement at r = 4mm, and an applied outer pressure of 2MPa.
# The radial stress is largest in the inner most element and, at an assumed
# mid element coordinate of 4.5mm, is equal to -2.545MPa.

# This is a demonstration of a simple thermomechanics simulation using
# XFEM in which a single crack propagates based on a principal stress
# criterion.
#
# The top and bottom of the plate are fixed in the y direction, and the
# top of the plate is cooled down over time. The thermal contraction
# causes tensile stresses, which lead to crack propagation. The crack
# propagates in a curved path because of the changinging nature of
# the thermal gradient as a result of the crack. There is no heat
# conduction across the crack as soon as it forms.

# Poroelastic response of a borehole.
#
# HIGHRES VERSION: this version gives good agreement with the analytical solution, but it takes a while so is a "heavy" test
#
# A fully-saturated medium contains a fluid with a homogeneous porepressure,
# but an anisitropic insitu stress. A infinitely-long borehole aligned with
# the $$z$$ axis is instanteously excavated. The borehole boundary is
# stress-free and allowed to freely drain. This problem is analysed using
# plane-strain conditions (no $$z$$ displacement).
#
# The solution in Laplace space is found in E Detournay and AHD Cheng "Poroelastic response of a borehole in a non-hydrostatic stress field". International Journal of Rock Mechanics and Mining Sciences and Geomechanics Abstracts 25 (1988) 171-182. In the small-time limit, the Laplace transforms may be performed. There is one typo in the paper. Equation (A4)'s final term should be -(a/r)\sqrt(4ct/(a^2\pi)), and not +(a/r)\sqrt(4ct/(a^2\pi)).
#
# Because realistic parameters are chosen (below),
# the residual for porepressure is much smaller than
# the residuals for the displacements. Therefore the
# scaling parameter is chosen. Also note that the
# insitu stresses are effective stresses, not total
# stresses, but the solution in the above paper is
# expressed in terms of total stresses.
#
# Here are the problem's parameters, and their values:
# Borehole radius. a = 1
# Rock's Lame lambda. la = 0.5E9
# Rock's Lame mu, which is also the Rock's shear modulus. mu = G = 1.5E9
# Rock bulk modulus. K = la + 2*mu/3 = 1.5E9
# Drained Poisson ratio. nu = (3K - 2G)/(6K + 2G) = 0.125
# Rock bulk compliance. 1/K = 0.66666666E-9
# Fluid bulk modulus. Kf = 0.7171315E9
# Fluid bulk compliance. 1/Kf = 1.39444444E-9
# Rock initial porosity. phi0 = 0.3
# Biot coefficient. alpha = 0.65
# Biot modulus. M = 1/(phi0/Kf + (alpha - phi0)(1 - alpha)/K) = 2E9
# Undrained bulk modulus. Ku = K + alpha^2*M = 2.345E9
# Undrained Poisson ratio. nuu = (3Ku - 2G)/(6Ku + 2G) = 0.2364
# Skempton coefficient. B = alpha*M/Ku = 0.554
# Fluid mobility (rock permeability/fluid viscosity). k = 1E-12

(modules/tensor_mechanics/test/tests/thermal_expansion/multiple_thermal_eigenstrains.i)
# The primary purpose of this test is to verify that the ability to combine
# multiple eigenstrains works correctly. It should behave identically to the
# constant_expansion_coeff.i model in this directory. Instead of applying the
# thermal expansion in one eigenstrain, it splits that into two eigenstrains
# that get added together.
# This test involves only thermal expansion strains on a 2x2x2 cube of approximate
# steel material. An initial temperature of 25 degrees C is given for the material,
# and an auxkernel is used to calculate the temperature in the entire cube to
# raise the temperature each time step. After the first timestep,in which the
# temperature jumps, the temperature increases by 6.25C each timestep.
# The thermal strain increment should therefore be
# 6.25 C * 1.3e-5 1/C = 8.125e-5 m/m.

# displacement is zero at the top. The acceleration of gravity is 20.
#
# The material has a Young's modulus of 1e6 and a density of 2.
#
# The analytic solution for the displacement along the bar is:
#
# u(y) = -b*y^2/(2*E)+b*L*y/E
#
# The displacement at y=L is b*L^2/(2*E) = 2*20*10*10/(2*1e6) = 0.002.
#
# The analytic solution for the stress along the bar assuming linear
# elasticity is:
#
# S(y) = b*(L-y)
#
# The stress at x=0 is b*L = 2*20*10 = 400.
#
# Note: The simulation does not measure stress at y=0. The stress
# is reported at element centers. The element closest to y=0 sits
# at y = 1/4 and has a stress of 390. This matches the linear
# stress distribution that is expected. The same situation applies
# at y = L where the stress is zero analytically. The nearest
# element is at y=9.75 where the stress is 10.

# ---------------------------------------------------------------------------
# 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.

# 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 problem from [Wilson 1979] tests the thermal strain term in the
#interaction integral. In this variant of this test, rather than using the
#standard mechanism for applying thermal strain, the eigenstrain for the
#thermal strain is applied using a generic object, which also supplies its
#gradient. This gradient is used in the interaction integral, with a nearly
#identical result to that from the version of this test that applies that
#in the standard manner.
#
#theta_e = 10 degrees C; a = 252; E = 207000; nu = 0.3; alpha = 1.35e-5
#
#With uniform_refine = 3, KI converges to
#KI = 5.602461e+02 (interaction integral)
#KI = 5.655005e+02 (J-integral)
#
#Both are in good agreement with [Shih 1986]:
#average_value = 0.4857 = KI / (sigma_theta * sqrt(pi * a))
#sigma_theta = E * alpha * theta_e / (1 - nu)
# = 207000 * 1.35e-5 * 10 / (1 - 0.3) = 39.9214
#KI = average_value * sigma_theta * sqrt(pi * a) = 5.656e+02

# 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

/**
* ComputeMultipleInelasticStress computes the stress, the consistent tangent
* operator (or an approximation to it), and a decomposition of the strain
* into elastic and inelastic parts. By default finite strains are assumed.
*
* The elastic strain is calculated by subtracting the computed inelastic strain
* increment tensor from the mechanical strain tensor. Mechanical strain is
* considered as the sum of the elastic and inelastic (plastic, creep, ect) strains.
*
* This material is used to call the recompute iterative materials of a number
* of specified inelastic models that inherit from StressUpdateBase. It iterates
* over the specified inelastic models until the change in stress is within
* a user-specified tolerance, in order to produce the stress, the consistent
* tangent operator and the elastic and inelastic strains for the time increment.
