Compute Linear Elastic Stress
Compute stress using elasticity for small strains
Description
This material, ComputeLinearElasticStress computes the elastic stress for a total and small strain formulation: this stress class is compatible with the ComputeSmallStrain type of strain calculators, including those for non-Cartesian coordinate systems. This stress calculator class can be used with any coordinate system to calculate the elastic stress response for a small total formulation strain.
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 where is the total strain formulation; this strain measure is also the sum of the mechanical elastic strain and any eigenstrains in the system.

# Identical to pp_generation_unconfined_fullysat_volume.i but using an Action
#
# A sample is constrained on all sides, except its top
# and its boundaries are
# also impermeable. Fluid is pumped into the sample via a
# volumetric source (ie m^3/second per cubic meter), and the
# rise in the top surface, porepressure, and stress are observed.
#
# In the standard poromechanics scenario, the Biot Modulus is held
# fixed and the source has units 1/s. Then the expected result
# is
# strain_zz = disp_z = BiotCoefficient*BiotModulus*s*t/((bulk + 4*shear/3) + BiotCoefficient^2*BiotModulus)
# porepressure = BiotModulus*(s*t - BiotCoefficient*strain_zz)
# stress_xx = (bulk - 2*shear/3)*strain_zz (remember this is effective stress)
# stress_zz = (bulk + 4*shear/3)*strain_zz (remember this is effective stress)
#
# In standard porous_flow, everything is based on mass, eg the source has
# units kg/s/m^3. This is discussed in the other pp_generation_unconfined
# models. In this test, we use the FullySaturated Kernel and set
# multiply_by_density = false
# meaning the fluid Kernel has units of volume, and the source, s, has units 1/time
#
# The ratios are:
# stress_xx/strain_zz = (bulk - 2*shear/3) = 1 (for the parameters used here)
# stress_zz/strain_zz = (bulk + 4*shear/3) = 4 (for the parameters used here)
# porepressure/strain_zz = 13.3333333 (for the parameters used here)
#
# Expect
# disp_z = 0.3*10*s*t/((2 + 4*1.5/3) + 0.3^2*10) = 0.612245*s*t
# porepressure = 10*(s*t - 0.3*0.612245*s*t) = 8.163265*s*t
# stress_xx = (2 - 2*1.5/3)*0.612245*s*t = 0.612245*s*t
# stress_zz = (2 + 4*shear/3)*0.612245*s*t = 2.44898*s*t

# Terzaghi's problem of consolodation of a drained medium
#
# A saturated soil sample sits in a bath of water.
# It is constrained on its sides, and bottom.
# Its sides and bottom are also impermeable.
# Initially it is unstressed.
# A normal stress, q, is applied to the soil's top.
# The soil then slowly compresses as water is squeezed
# out from the sample from its top (the top BC for
# the porepressure is porepressure = 0).
#
# See, for example. Section 2.2 of the online manuscript
# Arnold Verruijt "Theory and Problems of Poroelasticity" Delft University of Technology 2013
# but note that the "sigma" in that paper is the negative
# of the stress in TensorMechanics
#
# Here are the problem's parameters, and their values:
# Soil height. h = 10
# Soil's Lame lambda. la = 2
# Soil's Lame mu, which is also the Soil's shear modulus. mu = 3
# Soil bulk modulus. K = la + 2*mu/3 = 4
# Soil confined compressibility. m = 1/(K + 4mu/3) = 0.125
# Soil bulk compliance. 1/K = 0.25
# Fluid bulk modulus. Kf = 8
# Fluid bulk compliance. 1/Kf = 0.125
# Fluid mobility (soil permeability/fluid viscosity). k = 1.5
# Soil initial porosity. phi0 = 0.1
# Biot coefficient. alpha = 0.6
# Soil initial storativity, which is the reciprocal of the initial Biot modulus. S = phi0/Kf + (alpha - phi0)(1 - alpha)/K = 0.0625
# Consolidation coefficient. c = k/(S + alpha^2 m) = 13.95348837
# Normal stress on top. q = 1
# Initial porepressure, resulting from instantaneous application of q, assuming corresponding instantaneous increase of porepressure (Note that this is calculated by MOOSE: we only need it for the analytical solution). p0 = alpha*m*q/(S + alpha^2 m) = 0.69767442
# Initial vertical displacement (down is positive), resulting from instantaneous application of q (Note this is calculated by MOOSE: we only need it for the analytical solution). uz0 = q*m*h*S/(S + alpha^2 m)
# Final vertical displacement (down in positive) (Note this is calculated by MOOSE: we only need it for the analytical solution). uzinf = q*m*h
#
# The solution for porepressure is
# P = 4*p0/\pi \sum_{k=1}^{\infty} \frac{(-1)^{k-1}}{2k-1} \cos ((2k-1)\pi z/(2h)) \exp(-(2k-1)^2 \pi^2 ct/(4 h^2))
# This series converges very slowly for ct/h^2 small, so in that domain
# P = p0 erf( (1-(z/h))/(2 \sqrt(ct/h^2)) )
#
# The degree of consolidation is defined as
# U = (uz - uz0)/(uzinf - uz0)
# where uz0 and uzinf are defined above, and
# uz = the vertical displacement of the top (down is positive)
# U = 1 - (8/\pi^2)\sum_{k=1}^{\infty} \frac{1}{(2k-1)^2} \exp(-(2k-1)^2 \pi^2 ct/(4 h^2))

#
# 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.

# 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

# Constraining secondary nodes to move a linear combination of primary nodes
#
# The test consists of a 2D rectangular block divided into two Quad elements
# (along its height) which have different material properties.
# A displacement of 2 m is applied to the top surface of the block in x direction and the
# bottom surface is held fixed.
# The nodes of the interface between the two elements will tend to move as
# dictated by the material models of the two elements.
# LinearNodalConstraint forces the interface nodes to move as a linear combination
# of the nodes on the top and bottom of the block.
# primary node ids and the corresponding weights are taken as input by the LinearNodalConstraint
# along with the secondary node set or secondary node ids.
# The constraint can be applied using either penalty or kinematic formulation.
# In this example, the final x displacement of the top surface is 2m and bottom surface is 0m.
# Therefore, the final x displacement of the interface nodes would be 0.25*top+0.75*bottom = 0.5m

# Pattern example 1
#
# Phase changes driven by a combination mechanical (elastic) and chemical
# driving forces. In this three phase system a matrix phase, an oversized and
# an undersized precipitate phase compete. The chemical free energy favors a
# phase separation into either precipitate phase. A mix of both precipitate
# emerges to balance lattice expansion and contraction.
#
# This example demonstrates the use of
# * ACMultiInterface
# * SwitchingFunctionConstraintEta and SwitchingFunctionConstraintLagrange
# * DerivativeParsedMaterial
# * ElasticEnergyMaterial
# * DerivativeMultiPhaseMaterial
# * MultiPhaseStressMaterial
# which are the components to se up a phase field model with an arbitrary number
# of phases

# porepressure = BiotModulus*(s*t - BiotCoefficient*strain_zz)
# stress_xx = (bulk - 2*shear/3)*strain_zz (remember this is effective stress)
# stress_zz = (bulk + 4*shear/3)*strain_zz (remember this is effective stress)
#
# In standard porous_flow, everything is based on mass, eg the source has
# units kg/s/m^3. This is discussed in the other pp_generation_unconfined
# models. In this test, we use the FullySaturated Kernel and set
# multiply_by_density = false
# meaning the fluid Kernel has units of volume, and the source, s, has units 1/time
#
# The ratios are:
# stress_xx/strain_zz = (bulk - 2*shear/3) = 1 (for the parameters used here)
# stress_zz/strain_zz = (bulk + 4*shear/3) = 4 (for the parameters used here)
# porepressure/strain_zz = 13.3333333 (for the parameters used here)
#
# Expect
# disp_z = 0.3*10*s*t/((2 + 4*1.5/3) + 0.3^2*10) = 0.612245*s*t
# porepressure = 10*(s*t - 0.3*0.612245*s*t) = 8.163265*s*t
# stress_xx = (2 - 2*1.5/3)*0.612245*s*t = 0.612245*s*t
# stress_zz = (2 + 4*shear/3)*0.612245*s*t = 2.44898*s*t

# 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

# 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.

# 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).

# 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 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.

# Mandel's problem of consolodation of a drained medium
# Using the FullySaturatedDarcyBase and FullySaturatedMassTimeDerivative kernels
#
# 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

# 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.

#
# 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

# Using a BasicTHM action
# Terzaghi's problem of consolodation of a drained medium
# The FullySaturated Kernels are used, with multiply_by_density = false
# so that this becomes a linear problem with constant Biot Modulus
#
# A saturated soil sample sits in a bath of water.
# It is constrained on its sides, and bottom.
# Its sides and bottom are also impermeable.
# Initially it is unstressed.
# A normal stress, q, is applied to the soil's top.
# The soil then slowly compresses as water is squeezed
# out from the sample from its top (the top BC for
# the porepressure is porepressure = 0).
#
# See, for example. Section 2.2 of the online manuscript
# Arnold Verruijt "Theory and Problems of Poroelasticity" Delft University of Technology 2013
# but note that the "sigma" in that paper is the negative
# of the stress in TensorMechanics
#
# Here are the problem's parameters, and their values:
# Soil height. h = 10
# Soil's Lame lambda. la = 2
# Soil's Lame mu, which is also the Soil's shear modulus. mu = 3
# Soil bulk modulus. K = la + 2*mu/3 = 4
# Soil confined compressibility. m = 1/(K + 4mu/3) = 0.125

# Under these conditions
# porepressure = -(Biot coefficient)*(Biot modulus)*disp_z/L
# stress_xx = (bulk - 2*shear/3)*disp_z/L (remember this is effective stress)

# Parameters:
# Biot coefficient = 0.3
# Porosity = 0.1
# Bulk modulus = 2
# Shear modulus = 1.5
# fluid bulk modulus = 1/0.3 = 3.333333

# Scalar torque reaction
# This test computes the sum of the torques acting on a ten element 2D bar mesh
# and is intended to replicate the classical wrench problem from statics.
# A displacement in the y along the right face is applied to the bar end to create
# a shear force along the bar end. The rotation origin default (the global origin)
# and the axis of rotation direction vector used to compute the torque reaction
# is set to (0, 0, 1) out of the plane.
# Torque is calculated for the two nodes on the left of the bar. For the bottom
# node on the right, the torque/ moment lever is the x coordinate value, and for
# the top node on the right the torque lever is the hypotenuse of the x and y
# coordinates. The expected sum of the torque reaction is just over 37.

# 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 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.

# Terzaghi's problem of consolodation of a drained medium
#
# A saturated soil sample sits in a bath of water.
# It is constrained on its sides, and bottom.
# Its sides and bottom are also impermeable.
# Initially it is unstressed.
# A normal stress, q, is applied to the soil's top.
# The soil then slowly compresses as water is squeezed
# out from the sample from its top (the top BC for
# the porepressure is porepressure = 0).
#
# See, for example. Section 2.2 of the online manuscript
# Arnold Verruijt "Theory and Problems of Poroelasticity" Delft University of Technology 2013
# but note that the "sigma" in that paper is the negative
# of the stress in TensorMechanics
#
# Here are the problem's parameters, and their values:
# Soil height. h = 10
# Soil's Lame lambda. la = 2
# Soil's Lame mu, which is also the Soil's shear modulus. mu = 3
# Soil bulk modulus. K = la + 2*mu/3 = 4
# Soil confined compressibility. m = 1/(K + 4mu/3) = 0.125
# Soil bulk compliance. 1/K = 0.25
# Fluid bulk modulus. Kf = 8
# Fluid bulk compliance. 1/Kf = 0.125
# Fluid mobility (soil permeability/fluid viscosity). k = 1.5
# Soil initial porosity. phi0 = 0.1
# Biot coefficient. alpha = 0.6
# Soil initial storativity, which is the reciprocal of the initial Biot modulus. S = phi0/Kf + (alpha - phi0)(1 - alpha)/K = 0.0625
# Consolidation coefficient. c = k/(S + alpha^2 m) = 13.95348837
# Normal stress on top. q = 1
# Initial porepressure, resulting from instantaneous application of q, assuming corresponding instantaneous increase of porepressure (Note that this is calculated by MOOSE: we only need it for the analytical solution). p0 = alpha*m*q/(S + alpha^2 m) = 0.69767442
# Initial vertical displacement (down is positive), resulting from instantaneous application of q (Note this is calculated by MOOSE: we only need it for the analytical solution). uz0 = q*m*h*S/(S + alpha^2 m)
# Final vertical displacement (down in positive) (Note this is calculated by MOOSE: we only need it for the analytical solution). uzinf = q*m*h
#
# The solution for porepressure is
# P = 4*p0/\pi \sum_{k=1}^{\infty} \frac{(-1)^{k-1}}{2k-1} \cos ((2k-1)\pi z/(2h)) \exp(-(2k-1)^2 \pi^2 ct/(4 h^2))
# This series converges very slowly for ct/h^2 small, so in that domain
# P = p0 erf( (1-(z/h))/(2 \sqrt(ct/h^2)) )
#
# The degree of consolidation is defined as
# U = (uz - uz0)/(uzinf - uz0)
# where uz0 and uzinf are defined above, and
# uz = the vertical displacement of the top (down is positive)
# U = 1 - (8/\pi^2)\sum_{k=1}^{\infty} \frac{1}{(2k-1)^2} \exp(-(2k-1)^2 \pi^2 ct/(4 h^2))
#
# 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).

# Terzaghi's problem of consolodation of a drained medium
#
# A saturated soil sample sits in a bath of water.
# It is constrained on its sides, and bottom.
# Its sides and bottom are also impermeable.
# Initially it is unstressed.
# A normal stress, q, is applied to the soil's top.
# The soil then slowly compresses as water is squeezed
# out from the sample from its top (the top BC for
# the porepressure is porepressure = 0).
#
# See, for example. Section 2.2 of the online manuscript
# Arnold Verruijt "Theory and Problems of Poroelasticity" Delft University of Technology 2013
# but note that the "sigma" in that paper is the negative
# of the stress in TensorMechanics
#
# Here are the problem's parameters, and their values:
# Soil height. h = 10
# Soil's Lame lambda. la = 2
# Soil's Lame mu, which is also the Soil's shear modulus. mu = 3
# Soil bulk modulus. K = la + 2*mu/3 = 4
# Soil confined compressibility. m = 1/(K + 4mu/3) = 0.125
# Soil bulk compliance. 1/K = 0.25
# Fluid bulk modulus. Kf = 8
# Fluid bulk compliance. 1/Kf = 0.125
# Fluid mobility (soil permeability/fluid viscosity). k = 1.5
# Soil initial porosity. phi0 = 0.1
# Biot coefficient. alpha = 0.6
# Soil initial storativity, which is the reciprocal of the initial Biot modulus. S = phi0/Kf + (alpha - phi0)(1 - alpha)/K = 0.0625
# Consolidation coefficient. c = k/(S + alpha^2 m) = 13.95348837
# Normal stress on top. q = 1
# Initial porepressure, resulting from instantaneous application of q, assuming corresponding instantaneous increase of porepressure (Note that this is calculated by MOOSE: we only need it for the analytical solution). p0 = alpha*m*q/(S + alpha^2 m) = 0.69767442
# Initial vertical displacement (down is positive), resulting from instantaneous application of q (Note this is calculated by MOOSE: we only need it for the analytical solution). uz0 = q*m*h*S/(S + alpha^2 m)
# Final vertical displacement (down in positive) (Note this is calculated by MOOSE: we only need it for the analytical solution). uzinf = q*m*h
#
# The solution for porepressure is
# P = 4*p0/\pi \sum_{k=1}^{\infty} \frac{(-1)^{k-1}}{2k-1} \cos ((2k-1)\pi z/(2h)) \exp(-(2k-1)^2 \pi^2 ct/(4 h^2))
# This series converges very slowly for ct/h^2 small, so in that domain
# P = p0 erf( (1-(z/h))/(2 \sqrt(ct/h^2)) )
#
# The degree of consolidation is defined as
# U = (uz - uz0)/(uzinf - uz0)
# where uz0 and uzinf are defined above, and
# uz = the vertical displacement of the top (down is positive)
# U = 1 - (8/\pi^2)\sum_{k=1}^{\infty} \frac{1}{(2k-1)^2} \exp(-(2k-1)^2 \pi^2 ct/(4 h^2))

# Scalar torque reaction
# This test computes the sum of the torques acting on a single element cube mesh.
# Equal displacements in the x and the z are applied along the cube top to
# create a shear force along the (1, 0, 1) direction. The rotation origin is
# set to the middle of the bottom face of the cube (0.5, 0, 0.5), and the axis of
# rotation direction vector used to compute the torque reaction is set to (-1, 0, 1).
# Torque is calculated for the four nodes on the top of the cube. The projection
# of the node coordinates is zero for nodes 3 and 6, +1 for node 7, and -1 for
# node 2 from the selection of the direction vector and the rotation axis origin.

# 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.

# 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
#
# 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

# 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
# is 0.2 s.

# 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
#
# 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

# 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

# Patch Test for second order hex elements (HEX20)
#
# From Abaqus, Verification Manual, 1.5.2
#
# 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 on all exterior nodes using the functions,
#
# ux = 1e-4 * (2x + y + z) / 2
# uy = 1e-4 * (x + 2y + z) / 2
# ux = 1e-4 * (x + y + 2z) / 2
#
# giving uniform strains of
#
# exx = eyy = ezz = 2*exy = 2*eyz = 2*exz = 1e-4
#
#
# Hooke's Law provides an analytical solution for the uniform stress state.
# For example,
#
# stress xx = lambda(exx + eyy + ezz) + 2 * G * exx
# stress xy = 2 * G * exy
#
# where:
#
# lambda = (2 * G * nu) / (1 - 2 * nu)
# G = 0.5 * E / (1 + nu)
#
# For the test below, E = 1e6 and nu = 0.25, giving lambda = G = 4e5
#
# Thus
#
# stress xx = 4e5 * (3e-4) + 2 * 4e5 * 1e-4 = 200
# stress xy = 2 * 4e5 * 1e-4 / 2 = 40

(modules/porous_flow/test/tests/energy_conservation/heat04.i)
# The sample is a single unit element, with fixed displacements on
# all sides. A heat source of strength S (J/m^3/s) is applied into
# the element. There is no fluid flow or heat flow. The rise
# in temperature, porepressure and stress, and the change in porosity is
# matched with theory.
#
# In this case, fluid mass must be conserved, and there is no
# volumetric strain, so
# porosity * fluid_density = constant
# Also, the energy-density in the rock-fluid system increases with S:
# d/dt [(1 - porosity) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T] = S
# Also, the porosity evolves according to THM as
# porosity = biot + (porosity0 - biot) * exp( (biot - 1) * P / fluid_bulk + rock_thermal_exp * T)
# Finally, the effective stress must be exactly zero (as there is
# no strain).
#
# Let us assume that
# fluid_density = dens0 * exp(P / fluid_bulk - fluid_thermal_exp * T)
# Then the conservation of fluid mass means
# porosity = por0 * exp(- P / fluid_bulk + fluid_thermal_exp * T)
# where dens0 * por0 = the initial fluid mass.
# The last expression for porosity, combined with the THM one,
# and assuming that biot = 1 for simplicity, gives
# porosity = 1 + (porosity0 - 1) * exp(rock_thermal_exp * T) = por0 * exp(- P / fluid_bulk + fluid_thermal_exp * T) .... (A)
#
# This stuff may be substituted into the heat energy-density equation:
# S = d/dt [(1 - porosity0) * exp(rock_thermal_exp * T) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T]
#
# If S is constant then
# S * t = (1 - porosity0) * exp(rock_thermal_exp * T) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T
# with T(t=0) = 0 then Eqn(A) implies that por0 = porosity0 and
# P / fluid_bulk = fluid_thermal_exp * T - log(1 + (por0 - 1) * exp(rock_thermal_exp * T)) + log(por0)
#
# Parameters:
# A = 2
# fluid_bulk = 2.0
# dens0 = 3.0
# fluid_thermal_exp = 0.5
# fluid_heat_cap = 2
# por0 = 0.5

# 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.

# 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.

# x = 0 left
# x = 1 right

# Result: The displacement at the top node in the z direction should match

# 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.

# A sample is constrained on all sides, except its top
# and its boundaries are
# also impermeable. Fluid is pumped into the sample via a
# volumetric source (ie kg/second per cubic meter), and the
# rise in the top surface, porepressure, and stress are observed.
#
# In the standard poromechanics scenario, the Biot Modulus is held
# fixed and the source, s, has units m^3/second/m^3. Then the expected result
# is
# strain_zz = disp_z = BiotCoefficient*BiotModulus*s*t/((bulk + 4*shear/3) + BiotCoefficient^2*BiotModulus)
# porepressure = BiotModulus*(s*t - BiotCoefficient*strain_zz)
# stress_xx = (bulk - 2*shear/3)*strain_zz (remember this is effective stress)
# stress_zz = (bulk + 4*shear/3)*strain_zz (remember this is effective stress)
#
# In porous_flow, however, the source has units kg/second/m^3. The ratios remain
# fixed:
# stress_xx/strain_zz = (bulk - 2*shear/3) = 1 (for the parameters used here)
# stress_zz/strain_zz = (bulk + 4*shear/3) = 4 (for the parameters used here)
# porepressure/strain_zz = 13.3333333 (for the parameters used here)
#
# Expect
# disp_z = 0.3*10*s*t/((2 + 4*1.5/3) + 0.3^2*10) = 0.612245*s*t
# porepressure = 10*(s*t - 0.3*0.612245*s*t) = 8.163265*s*t
# stress_xx = (2 - 2*1.5/3)*0.612245*s*t = 0.612245*s*t
# stress_zz = (2 + 4*shear/3)*0.612245*s*t = 2.44898*s*t

# The equation of motion in terms of matrices is:

# heat04, but using an action
#
# The sample is a single unit element, with fixed displacements on
# all sides. A heat source of strength S (J/m^3/s) is applied into
# the element. There is no fluid flow or heat flow. The rise
# in temperature, porepressure and stress, and the change in porosity is
# matched with theory.
#
# In this case, fluid mass must be conserved, and there is no
# volumetric strain, so
# porosity * fluid_density = constant
# Also, the energy-density in the rock-fluid system increases with S:
# d/dt [(1 - porosity) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T] = S
# Also, the porosity evolves according to THM as
# porosity = biot + (porosity0 - biot) * exp( (biot - 1) * P / fluid_bulk + rock_thermal_exp * T)
# Finally, the effective stress must be exactly zero (as there is
# no strain).
#
# Let us assume that
# fluid_density = dens0 * exp(P / fluid_bulk - fluid_thermal_exp * T)
# Then the conservation of fluid mass means
# porosity = por0 * exp(- P / fluid_bulk + fluid_thermal_exp * T)
# where dens0 * por0 = the initial fluid mass.
# The last expression for porosity, combined with the THM one,
# and assuming that biot = 1 for simplicity, gives
# porosity = 1 + (porosity0 - 1) * exp(rock_thermal_exp * T) = por0 * exp(- P / fluid_bulk + fluid_thermal_exp * T) .... (A)
#
# This stuff may be substituted into the heat energy-density equation:
# S = d/dt [(1 - porosity0) * exp(rock_thermal_exp * T) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T]
#
# If S is constant then
# S * t = (1 - porosity0) * exp(rock_thermal_exp * T) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T
# with T(t=0) = 0 then Eqn(A) implies that por0 = porosity0 and
# P / fluid_bulk = fluid_thermal_exp * T - log(1 + (por0 - 1) * exp(rock_thermal_exp * T)) + log(por0)
#
# Parameters:
# A = 2
# fluid_bulk = 2.0

# Testing StickyBC
#
# Push the top of an element downward until the bottom hits an (invisible) obstruction.
# 10 timesteps are used. In each timestep disp_y is decreased by 0.1. The
# StickyBC has a min_value of -0.49, so at timestep 5 this bound will be violated
# and the bottom boundary will be fixed forever after.
#
# This test also illustrates that StickyBC is only ever meant to be used in
# special situations:
# - if, after the simulation ends, the top is moved upward again, the StickyBC
# will keep the bottom fixed. Ie, the StickyBC is truly "sticky".
# - setting min_value = -0.5 in this test illustrates the "approximate" nature
# of StickyBC, in that some nodes will be fixed at disp_y=-0.5, while others
# will be fixed at disp_y=-0.6, due to the timestepping and roundoff errors
# in MOOSE's solution.

# fluid_density = dens0 * exp(P / fluid_bulk - fluid_thermal_exp * T)
# Then the conservation of fluid mass means
# porosity = por0 * exp(- P / fluid_bulk + fluid_thermal_exp * T)
# where dens0 * por0 = the initial fluid mass.
# The last expression for porosity, combined with the THM one,
# and assuming that biot = 1 for simplicity, gives
# porosity = 1 + (porosity0 - 1) * exp(rock_thermal_exp * T) = por0 * exp(- P / fluid_bulk + fluid_thermal_exp * T) .... (A)
#
# This stuff may be substituted into the heat energy-density equation:
# S = d/dt [(1 - porosity0) * exp(rock_thermal_exp * T) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T]
#
# If S is constant then
# S * t = (1 - porosity0) * exp(rock_thermal_exp * T) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T
# with T(t=0) = 0 then Eqn(A) implies that por0 = porosity0 and
# P / fluid_bulk = fluid_thermal_exp * T - log(1 + (por0 - 1) * exp(rock_thermal_exp * T)) + log(por0)
#
# Parameters:
# A = 2
# fluid_bulk = 2.0
# dens0 = 3.0
# fluid_thermal_exp = 0.5
# fluid_heat_cap = 2
# por0 = 0.5
# rock_thermal_exp = 0.25
# rock_density = 5
# rock_heat_capacity = 0.2

# The sample is a single unit element, with roller BCs on the sides
# and bottom. A constant displacement is applied to the top: disp_z = -0.01*t.
# There is no fluid flow or heat flow.
# Heat energy conservation is checked.
#
# Under these conditions (here L is the height of the sample: L=1 in this case):
# porepressure = porepressure(t=0) - (Fluid bulk modulus)*log(1 - 0.01*t)
# stress_xx = (bulk - 2*shear/3)*disp_z/L (remember this is effective stress)
# stress_zz = (bulk + 4*shear/3)*disp_z/L (remember this is effective stress)
# Also, the total heat energy must be conserved: this is
# fluid_mass * fluid_heat_cap * temperature + (1 - porosity) * rock_density * rock_heat_cap * temperature * volume
# Since fluid_mass is conserved, and volume = (1 - 0.01*t), this can be solved for temperature:
# temperature = initial_heat_energy / (fluid_mass * fluid_heat_cap + (1 - porosity) * rock_density * rock_heat_cap * (1 - 0.01*t))
#
# Parameters:
# Bulk modulus = 2
# Shear modulus = 1.5
# fluid bulk modulus = 0.5
# initial porepressure = 0.1
# initial temperature = 10
#
# Desired output:
# zdisp = -0.01*t
# p0 = 0.1 - 0.5*log(1-0.01*t)
# stress_xx = stress_yy = -0.01*t
# stress_zz = -0.04*t
# t0 = 11.5 / (0.159 + 0.99 * (1 - 0.01*t))
#
# Regarding the "log" - it comes from preserving fluid mass

# and the top boundary will be fixed forever after.
#
# This test also illustrates that StickyBC is only ever meant to be used in
# special situations:
# - if, after the simulation ends, the bottom is moved downward again, the StickyBC
# will keep the top fixed. Ie, the StickyBC is truly "sticky".
# - setting max_value = 0.5 in this test illustrates the "approximate" nature
# of StickyBC, in that some nodes will be fixed at disp_y=0.5, while others
# will be fixed at disp_y=0.6, due to the timestepping and roundoff errors
# in MOOSE's solution.

# 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
# is 0.2 s.

# 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 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.

# A sample is constrained on all sides, except its top
# and its boundaries are
# also impermeable. Fluid is pumped into the sample via a
# volumetric source (ie kg/second per cubic meter), and the
# rise in the top surface, porepressure, and stress are observed.
#
# In the standard poromechanics scenario, the Biot Modulus is held
# fixed and the source has units 1/time. Then the expected result
# is
# strain_zz = disp_z = BiotCoefficient*BiotModulus*s*t/((bulk + 4*shear/3) + BiotCoefficient^2*BiotModulus)
# porepressure = BiotModulus*(s*t - BiotCoefficient*strain_zz)
# stress_xx = (bulk - 2*shear/3)*strain_zz (remember this is effective stress)
# stress_zz = (bulk + 4*shear/3)*strain_zz (remember this is effective stress)
#
# In porous_flow, however, the source has units kg/s/m^3 and the
# Biot Modulus is not held fixed. This means that disp_z, porepressure,
# etc are not linear functions of t. Nevertheless, the ratios remain
# fixed:
# stress_xx/strain_zz = (bulk - 2*shear/3) = 1 (for the parameters used here)
# stress_zz/strain_zz = (bulk + 4*shear/3) = 4 (for the parameters used here)

# A sample is constrained on all sides, except its top
# and its boundaries are
# also impermeable. Fluid is pumped into the sample via a
# volumetric source (ie kg/second per cubic meter), and the
# rise in the top surface, porepressure, and stress are observed.
#
# In the standard poromechanics scenario, the Biot Modulus is held
# fixed and the source has units 1/time. Then the expected result
# is
# strain_zz = disp_z = BiotCoefficient*BiotModulus*s*t/((bulk + 4*shear/3) + BiotCoefficient^2*BiotModulus)
# porepressure = BiotModulus*(s*t - BiotCoefficient*strain_zz)
# stress_xx = (bulk - 2*shear/3)*strain_zz (remember this is effective stress)
# stress_zz = (bulk + 4*shear/3)*strain_zz (remember this is effective stress)
#
# In porous_flow, however, the source has units kg/s/m^3. The ratios remain
# fixed:
# stress_xx/strain_zz = (bulk - 2*shear/3) = 1 (for the parameters used here)
# stress_zz/strain_zz = (bulk + 4*shear/3) = 4 (for the parameters used here)
# porepressure/strain_zz = 13.3333333 (for the parameters used here)
#
# Expect
# disp_z = 0.3*10*s*t/((2 + 4*1.5/3) + 0.3^2*10) = 0.612245*s*t
# porepressure = 10*(s*t - 0.3*0.612245*s*t) = 8.163265*s*t
# stress_xx = (2 - 2*1.5/3)*0.612245*s*t = 0.612245*s*t
# stress_zz = (2 + 4*shear/3)*0.612245*s*t = 2.44898*s*t
# The relationship between the constant poroelastic source
# s (m^3/second/m^3) and the PorousFlow source, S (kg/second/m^3) is

# A sample is constrained on all sides, except its top
# and its boundaries are
# also impermeable. Fluid is pumped into the sample via a
# volumetric source (ie kg/second per cubic meter), and the
# rise in the top surface, porepressure, and stress are observed.
#
# In the standard poromechanics scenario, the Biot Modulus is held
# fixed and the source, s, has units m^3/second/m^3. Then the expected result
# is
# strain_zz = disp_z = BiotCoefficient*BiotModulus*s*t/((bulk + 4*shear/3) + BiotCoefficient^2*BiotModulus)
# porepressure = BiotModulus*(s*t - BiotCoefficient*strain_zz)
# stress_xx = (bulk - 2*shear/3)*strain_zz (remember this is effective stress)
# stress_zz = (bulk + 4*shear/3)*strain_zz (remember this is effective stress)
#
# In porous_flow, however, the source has units kg/second/m^3. The ratios remain
# fixed:
# stress_xx/strain_zz = (bulk - 2*shear/3) = 1 (for the parameters used here)
# stress_zz/strain_zz = (bulk + 4*shear/3) = 4 (for the parameters used here)
# porepressure/strain_zz = 13.3333333 (for the parameters used here)
#
# Expect
# disp_z = 0.3*10*s*t/((2 + 4*1.5/3) + 0.3^2*10) = 0.612245*s*t
# porepressure = 10*(s*t - 0.3*0.612245*s*t) = 8.163265*s*t
# stress_xx = (2 - 2*1.5/3)*0.612245*s*t = 0.612245*s*t
# stress_zz = (2 + 4*shear/3)*0.612245*s*t = 2.44898*s*t
# The relationship between the constant poroelastic source
# s (m^3/second/m^3) and the PorousFlow source, S (kg/second/m^3) is
# S = fluid_density * s = s * exp(porepressure/fluid_bulk)

# Terzaghi's problem of consolodation of a drained medium
# The FullySaturated Kernels are used, with multiply_by_density = false
# so that this becomes a linear problem with constant Biot Modulus
#
# A saturated soil sample sits in a bath of water.
# It is constrained on its sides, and bottom.
# Its sides and bottom are also impermeable.
# Initially it is unstressed.
# A normal stress, q, is applied to the soil's top.
# The soil then slowly compresses as water is squeezed
# out from the sample from its top (the top BC for
# the porepressure is porepressure = 0).
#
# See, for example. Section 2.2 of the online manuscript
# Arnold Verruijt "Theory and Problems of Poroelasticity" Delft University of Technology 2013
# but note that the "sigma" in that paper is the negative
# of the stress in TensorMechanics
#
# Here are the problem's parameters, and their values:
# Soil height. h = 10
# Soil's Lame lambda. la = 2
# Soil's Lame mu, which is also the Soil's shear modulus. mu = 3
# Soil bulk modulus. K = la + 2*mu/3 = 4
# Soil confined compressibility. m = 1/(K + 4mu/3) = 0.125
# Soil bulk compliance. 1/K = 0.25
# Fluid bulk modulus. Kf = 8
# Fluid bulk compliance. 1/Kf = 0.125
# Fluid mobility (soil permeability/fluid viscosity). k = 1.5
# Soil initial porosity. phi0 = 0.1
# Biot coefficient. alpha = 0.6
# Soil initial storativity, which is the reciprocal of the initial Biot modulus. S = phi0/Kf + (alpha - phi0)(1 - alpha)/K = 0.0625
# Consolidation coefficient. c = k/(S + alpha^2 m) = 13.95348837
# Normal stress on top. q = 1
# Initial porepressure, resulting from instantaneous application of q, assuming corresponding instantaneous increase of porepressure (Note that this is calculated by MOOSE: we only need it for the analytical solution). p0 = alpha*m*q/(S + alpha^2 m) = 0.69767442
# Initial vertical displacement (down is positive), resulting from instantaneous application of q (Note this is calculated by MOOSE: we only need it for the analytical solution). uz0 = q*m*h*S/(S + alpha^2 m)
# Final vertical displacement (down in positive) (Note this is calculated by MOOSE: we only need it for the analytical solution). uzinf = q*m*h
#
# The solution for porepressure is
# P = 4*p0/\pi \sum_{k=1}^{\infty} \frac{(-1)^{k-1}}{2k-1} \cos ((2k-1)\pi z/(2h)) \exp(-(2k-1)^2 \pi^2 ct/(4 h^2))
# This series converges very slowly for ct/h^2 small, so in that domain
# P = p0 erf( (1-(z/h))/(2 \sqrt(ct/h^2)) )
#
# The degree of consolidation is defined as
# U = (uz - uz0)/(uzinf - uz0)
# where uz0 and uzinf are defined above, and
# uz = the vertical displacement of the top (down is positive)
# U = 1 - (8/\pi^2)\sum_{k=1}^{\infty} \frac{1}{(2k-1)^2} \exp(-(2k-1)^2 \pi^2 ct/(4 h^2))

# 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.

/**
* Computes the stress of a linear viscoelastic material, using total

* strain + the creep strain, the creep strain itself resulting from
* a spring-dashpot model.
*
* If you need to accomodate other sources of inelastic strains, use
* a ComputeMultipleInelasticStress material instead, associated with a
* LinearViscoelasticStressUpdate to represent the creep strain.
