ADComputeFiniteStrainElasticStress
Compute stress using elasticity for finite strains
Description
This material, ADComputeFiniteStrainElasticStress computes the elastic stress for an incremental formulation, both incremental small (ADComputeIncrementalSmallStrain type) and incremental finite (ADComputeFiniteStrain 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.

# This problem consists of two beams with different prescribed temperatures on

# bends downward due to thermal expansion.
# This is a test of the effectiveness of the Jacobian terms coupling temperature
# and displacement for thermal contact. The Jacobian is not exactly correct,

# 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

#
# 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.

# 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

# 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 (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.

#
# 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.

#
# 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.

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

# 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

# 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 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.

# 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.

/**
* ADComputeMultipleInelasticStress computes the stress 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 ADStressUpdateBase. It iterates
* over the specified inelastic models until the change in stress is within
* a user-specified tolerance, in order to produce the stress and the elastic and inelastic strains
* for the time increment.
