# 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

# 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

#
# 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.

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

# A circular domain has as uniform heat source that increases with time
# and a fixed temperature on the outer boundary, resulting in a temperature gradient.
# This results in heterogeneous thermal expansion, where it is pinned in the center.
# Looking at the hoop stress demonstrates why fuel pellets have radial cracks
# that extend from the outer boundary to about halfway through the radius.
# The problem is run with length units of microns.

(modules/solid_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.

#
# This problem is modified from the Abaqus verification manual:
# "1.5.4 Patch test for axisymmetric elements"
# The original stress solution is given as:
# xx = yy = zz = 2000
# xy = 400
#
# Here, E=1e6 and nu=0.25.
# However, with a +100 degree change in temperature and a coefficient
# of thermal expansion of 1e-6, the solution becomes:
# xx = yy = zz = 1800
# xy = 400
# since
# E*(1-nu)/(1+nu)/(1-2*nu)*(1+2*nu/(1-nu))*(1e-3-1e-4) = 1800
#
# Also,
#
# dSrr dSrz Srr-Stt
# ---- + ---- + ------- + br = 0
# dr dz r
#
# and
#
# dSrz Srz dSzz
# ---- + --- + ---- + bz = 0
# dr r dz
#
# where
# Srr = stress in rr
# Szz = stress in zz
# Stt = stress in theta-theta
# Srz = stress in rz
# br = body force in r direction
# bz = body force in z direction
#
# This test is meant to exercise the Jacobian. To that end, the body
# force has been turned off. This makes the results differ slightly
# from the original values, but requires a correct Jacobian for minimal
# iterations. Iteration plotting is turned on to ensure that the
# number of iterations needed does not increase.

# 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 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

#This problem from [Wilson 1979] tests the thermal strain term in the
#interaction integral
#
#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

# 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

#
# 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].

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

# 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 SolidMechanics QuasiStatic Physics,
# the QuasiStatic Physics 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.

# 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.

# The original stress solution is given as:
# xx = yy = zz = 2000
# xy = 400
#
# Here, E=1e6 and nu=0.25.
# However, with a +100 degree change in temperature and a coefficient
# of thermal expansion of 1e-6, the solution becomes:
# xx = yy = zz = 1800
# xy = 400
# since
# E*(1-nu)/(1+nu)/(1-2*nu)*(1+2*nu/(1-nu))*(1e-3-1e-4) = 1800

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

# 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

# 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 SolidMechanics QuasiStatic Physics,
# the QuasiStatic Physics 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.

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

# temperature jumps, the temperature increases by 6.25C each timestep.
# The thermal strain increment should therefore be

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