Rank Two Scalar Aux
Compute a scalar property of a RankTwoTensor
Description
This AuxKernel uses a set of functions to compute scalar quantities such as invariants and components in specified directions from rank-2 tensors such as stress or strain. See RankTwoScalarTools for further information.
Example Input File Syntax
[./vonmises]
type = RankTwoScalarAux
rank_two_tensor = stress
variable = vonmises
scalar_type = VonMisesStress
execute_on = timestep_end
[../]An AuxVariable is required to store the AuxKernel information. Note that the name of the AuxVariable is used as the argument for the variable input parameter in the RankTwoScalarAux block.
[./vonmises]
order = CONSTANT
family = MONOMIAL
[../]As with the RankTwoAux AuxKernel, RankTwoScalarAux requires the inclusion of an AuxVariable block for each AuxKernel block.
AuxVariable Order
commentnote:Elemental vs Nodal Visualization of Quadrature Field Values
Results will have different quality based on the AuxVariable:
Elemental Constant Monomial Using an AuxVariable with
family = MONOMIALandorder = CONSTANTwill give a constant value of the AuxVariable for the entire element, which is computed by taking a volume-weighted average of the integration point quantities. This is the default option using SolidMechanics Action and requires the least computational cost.Elemental Higher-order Monomial Using an AuxVariable with
family = MONOMIALandorder = FIRSTor higher will result in fields that vary linearly (or with higher order) within each element. Because the Exodus mesh format does not support higher-order elemental variables, these AuxVariables are output by libMesh as nodal variables for visualization purposes. Using higher order monomial variables in this way can produce smoother visualizations of results for a properly converged simulation.Nodal Lagrange Using an AuxVariable with
family = LAGRANGEwill result in a smooth nodal field of the material property, constructed using nodal patch recovery.patch_polynomial_orderis set to equal the order of the AuxVariable by default. Use this option for the best (smoothest, most accurate) results, but there is some additional computational cost. Furthermore, this method is suitable only for serial simulations at present.

Optional Parameters
- control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector<std::string>
Controllable:No
Description:Adds user-defined labels for accessing object parameters via control logic.

- patch_polynomial_orderPolynomial order used in least squares fitting of material property over the local patch of elements connected to a given node
C++ Type:MooseEnum
Options:CONSTANT, FIRST, SECOND, THIRD, FOURTH
Controllable:No
Description:Polynomial order used in least squares fitting of material property over the local patch of elements connected to a given node
- search_methodnearest_node_connected_sidesChoice of search algorithm. All options begin by finding the nearest node in the primary boundary to a query point in the secondary boundary. In the default nearest_node_connected_sides algorithm, primary boundary elements are searched iff that nearest node is one of their nodes. This is fast to determine via a pregenerated node-to-elem map and is robust on conforming meshes. In the optional all_proximate_sides algorithm, primary boundary elements are searched iff they touch that nearest node, even if they are not topologically connected to it. This is more CPU-intensive but is necessary for robustness on any boundary surfaces which has disconnections (such as Flex IGA meshes) or non-conformity (such as hanging nodes in adaptively h-refined meshes).

# This test compares the hoop strain at two different elements in an internally
# pressurized cylinder with anisotropic plasticity: different yield condition
# for hoop and axial directions. The elements are located circumferentially
# apart but at same axial position. It is expected that due to pressurization
# hoop strains will develop with uniform magnitude along hoop direction. The
# test verifies that the plastic hoop strain is uniform in hoop direction.
# For 3D simulations with material properties oriented along the curved
# geometry such as cylinder or sphere, the stresses and strains are rotated to
# the local coordinate system from the global coordinate system. The plastic
# strain is calculated in the local coordinate system and then transformed to
# the global coordinate system. This test involves a 3D cylindrical geometry,
# and helps in indirectly verifying that this transformation of stresses and
# strains back and forth between the local and global coordinate system is
# correctly implemented.

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

# This test compares the hoop strain at two different elements in an internally
# pressurized cylinder with anisotropic plasticity: different yield condition
# for hoop and axial directions. The elements are located circumferentially
# apart but at same axial position. It is expected that due to pressurization
# hoop strains will develop with uniform magnitude along hoop direction. The
# test verifies that the plastic hoop strain is uniform in hoop direction.
# For 3D simulations with material properties oriented along the curved
# geometry such as cylinder or sphere, the stresses and strains are rotated to
# the local coordinate system from the global coordinate system. The plastic
# strain is calculated in the local coordinate system and then transformed to
# the global coordinate system. This test involves a 3D cylindrical geometry,
# and helps in indirectly verifying that this transformation of stresses and
# strains back and forth between the local and global coordinate system is
# correctly implemented.

# This test checks whether the ComputeReducedOrderEigenstrain is functioning properly.
#
# If instead of 'reduced_eigenstrain', 'thermal_eigenstrain' is given to
# eigenstrain_names in the Physics/SolidMechanics/QuasiStatic/all block, the output will be
# quite different.
#
# Open the reducedOrderRZLinear_out_hydro_0001.csv file and plot the hydro variables as
# a function of x. For the reduced order case, the values are smooth across each of the
# two elements with a jump upward from the left element to the right element. However,
# when not using 'reduced_order_eigenstrain', a jump downward appears from the left
# element to the right element.

# q = [F(S22-S33)^2 + G(S33-S11)^2 + H(S11-S22)^2 + 2L(S23)^2 + 2M(S13)^2 + 2N(S12)^2]^0.5
# S11 = 40 Pa and S22 = 40 MPa; other compoenents of stress are zero since it is a biaxial test
# F=0.5 G=0.25 H=0.3866 L=1.6413 M=1.6413 N=1.2731 (as used in this test)
# Substituting the values of stress components and F, G, H, L, M and N we obtain
# q = 34.64101615137755 Pa
#
# Equivalent_creep_strain_rate = A(q)^n (power law creep rate used in this test)
# Substituting A=1e-15 and n=9, and q as calculated above, we obtain
# Equivalent_creep_strain_rate = 0.07183161109149655
#
# The 11 (xx) and 22 (yy) components of creep_strain_tensor are calculated as below:
#
# creep_strain_tensor_11 = (Equivalent_creep_strain_rate / q) *
# (H * (S11 - S22) - G * (S33 - S11)) * time_increment
# creep_strain_tensor_22 = (Equivalent_creep_strain_rate / q) *
# (F * (S22 - S33) - H * (S11 - S22)) * time_increment
#
# Substituting the values and time_increment as 0.001 we obtain the analytical solution.

# Affine Plasticity Test for Transient Stress Eigenvalues with Stationary Eigenvectors
# This test is taken from K. Jamojjala, R. Brannon, A. Sadeghirad, J. Guilkey,
# "Verification tests in solid mechanics," Engineering with Computers, Vol 31.,
# p. 193-213.
# The test involves applying particular strains and expecting particular stresses.
# The material properties are:
# Yield in shear 165 MPa
# Shear modulus 79 GPa
# Poisson's ratio 1/3
# The strains are:
# Time e11 e22 e33
# 0 0 0 0
# 1 -0.003 -0.003 0.006
# 2 -0.0103923 0 0.0103923
# The expected stresses are:
# sigma11:
# -474*t 0 < t <= 0.201
# -95.26 0.201 < t <= 1
# (189.4+0.1704*sqrt(a)-0.003242*a)
# --------------------------------- 1 < t <= 2
# 1+0.00001712*a
# -189.4 t > 2 (paper erroneously gives a positive value)
#
# sigma22:
# -474*t 0 < t <= 0.201
# -95.26 0.201 < t <= 1
# -(76.87+1.443*sqrt(a)-0.001316*a)
# --------------------------------- 1 < t <= 2 (paper gives opposite sign)
# 1+0.00001712*a
# 76.87 t > 2
#
# sigma33:
# 948*t 0 < t <= 0.201
# 190.5 0.201 < t <= 1
# -(112.5-1.272*sqrt(a)-0.001926*a)

# Note: If planning to run this case with strain type ComputeFiniteStrain, the
# displacement function must be adjusted. Instead of
# strain = (l - l0)/l0 = (u+l0 - l0)/l0 = u/l0
# with l0=1.0, we would have
# strain = log(l/l0) = log((u+l0)/l0)
# with l0=1.0. So, for strain = -0.003,
# -0.003 = log((u+l0)/l0) ->
# u = exp(-0.003)*l0 - l0 = -0.0029955044966269995.

# recovers the specified volumetric expansion.
# This model applies volumetric strain that ramps from 0 to 2 to a unit cube
# and computes the final volume, which should be exactly 3. Note that the default
# TaylorExpansion option for decomposition_method gives a small (~4%) error
# with this very large incremental strain, but decomposition_method=EigenSolution

# This test compares the hoop strain at two different elements in an internally
# pressurized cylinder with anisotropic plasticity: different yield condition
# for hoop and axial directions. The elements are located circumferentially
# apart but at same axial position. It is expected that due to pressurization
# hoop strains will develop with uniform magnitude along hoop direction. The
# test verifies that the plastic hoop strain is uniform in hoop direction.
# For 3D simulations with material properties oriented along the curved
# geometry such as cylinder or sphere, the stresses and strains are rotated to
# the local coordinate system from the global coordinate system. The plastic
# strain is calculated in the local coordinate system and then transformed to
# the global coordinate system. This test involves a 3D cylindrical geometry,
# and helps in indirectly verifying that this transformation of stresses and
# strains back and forth between the local and global coordinate system is
# correctly implemented.

# 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

# Affine Plasticity Test for Transient Stress Eigenvalues with Stationary Eigenvectors
# This test is taken from K. Jamojjala, R. Brannon, A. Sadeghirad, J. Guilkey,
# "Verification tests in solid mechanics," Engineering with Computers, Vol 31.,
# p. 193-213.
# The test involves applying particular strains and expecting particular stresses.
# The material properties are:
# Yield in shear 165 MPa
# Shear modulus 79 GPa
# Poisson's ratio 1/3
# The strains are:
# Time e11 e22 e33
# 0 0 0 0
# 1 -0.003 -0.003 0.006
# 2 -0.0103923 0 0.0103923
# The expected stresses are:
# sigma11:
# -474*t 0 < t <= 0.201
# -95.26 0.201 < t <= 1
# (189.4+0.1704*sqrt(a)-0.003242*a)
# --------------------------------- 1 < t <= 2
# 1+0.00001712*a
# -189.4 t > 2 (paper erroneously gives a positive value)
#
# sigma22:
# -474*t 0 < t <= 0.201
# -95.26 0.201 < t <= 1
# -(76.87+1.443*sqrt(a)-0.001316*a)
# --------------------------------- 1 < t <= 2 (paper gives opposite sign)
# 1+0.00001712*a
# 76.87 t > 2
#
# sigma33:
# 948*t 0 < t <= 0.201
# 190.5 0.201 < t <= 1
# -(112.5-1.272*sqrt(a)-0.001926*a)
# --------------------------------- 1 < t <= 2 (paper has two sign errors here)
# 1+0.00001712*a
# 112.5 t > 2
#
# where a = exp(12.33*t).
#
# Note: If planning to run this case with strain type ComputeFiniteStrain, the
# displacement function must be adjusted. Instead of
# strain = (l - l0)/l0 = (u+l0 - l0)/l0 = u/l0
# with l0=1.0, we would have
# strain = log(l/l0) = log((u+l0)/l0)
# with l0=1.0. So, for strain = -0.003,
# -0.003 = log((u+l0)/l0) ->
# u = exp(-0.003)*l0 - l0 = -0.0029955044966269995.

# For uniaxial tensile loading in y-direction, the slope of the

# This test compares the hoop strain at two different elements in an internally
# pressurized cylinder with anisotropic plasticity: different yield condition
# for hoop and axial directions. The elements are located circumferentially
# apart but at same axial position. It is expected that due to pressurization
# hoop strains will develop with uniform magnitude along hoop direction. The
# test verifies that the plastic hoop strain is uniform in hoop direction.
# For 3D simulations with material properties oriented along the curved
# geometry such as cylinder or sphere, the stresses and strains are rotated to
# the local coordinate system from the global coordinate system. The plastic
# strain is calculated in the local coordinate system and then transformed to
# the global coordinate system. This test involves a 3D cylindrical geometry,
# and helps in indirectly verifying that this transformation of stresses and
# strains back and forth between the local and global coordinate system is
# correctly implemented.
