Compute Finite Strain in Cartesian System
Compute a strain increment and rotation increment for finite strains.
Description
This class is used to compute the strain increment, total strain, and incremental rotation for finite strain problems. The finite strain approach used is the incremental corotational form (Rashid, 1993). This approach computes logarithmic strains and strain increments.
Incremental Configurations
In this form, the generic time increment under consideration is such that (1) The configurations of the material element under consideration at and are denoted by , and , respectively for the previous and the current incremental configurations.
Deformation Gradient Definition
The deformation gradient represents the change in a material element from the reference configuration to the current configuration (Malvern, 1969). In the incremental formulation used in the ComputeFiniteStrain class, the incremental deformation gradient represents the change in the material element from the previous configuration, , to the current configuration, . Mathematically this relationship is given as where is the position vector of materials points in , and is the position vector of materials points in .
commentnote:Incremental vs Total Deformation Gradient
Note that is NOT the deformation gradient, but rather the incremental deformation gradient of with respect to . Thus , where is the total deformation gradient at time .
Following the explanation of this procedure given by Zhang et al. (2018), the incremental deformation gradient can be multiplicatively decomposed into an incremental rotation tensor, , and the incremental right stretch tensor, (2) where is a proper orthogonal rotation tensor and the stretch tensor, , is symmetric and positive definite. The incremental right Cauchy-Green deformation tensor, , can be given in terms of by substituting Eq. (2) into the definition for from Malvern (1969): (3) where the orthogonal nature of enables the simplification given above. Thus can be computed from as (4) which can be evaluated by performing a spectral decomposition of . Once has been computed, the multiplicative decomposition of the deformation gradient is used to find the incremental rotation tensor and the stretching rate . Following Rashid (1993), the stretching rate tensor can be expressed in terms of the 'incremental' right Cauchy-Green deformation tensor (5)
This incremental stretching rate tensor can then be used as the work conjugate for a stress measure, or used to compute another strain measure. The most computationally expensive part of this procedure is the spectral decomposition of to find . This decomposition can be computed exactly using an Eigensolution, yet an approximation of this can be computed with much lower computational expense using a Taylor expansion procedure. This class provides options to perform this calculation either way, and the Taylor expansion is the default.
This class also provides an additional option for computing the stretching rate tensor and incremental rotation tensor using the method of Hughes and Winget (1980). This method involves evaluating the displacement field at the midpoint of the timestep, and as a result, requires updating stress and strain measures at the old configuration rather than the current.
Taylor Expansion
The stretching rate tensor and incremental rotation matrix can be approximated using Taylor expansion as Rashid (1993): the approximated stretching rate tensor the approximated rotation matrix with The sign of is set by examining the sign of .
Eigen-Solution
The stretching rate tensor can be calculated by the eigenvalues and eigenvectors of . with being the eigenvalue and matrix being constructed from the corresponding eigenvector. the 'incremental' stretching tensor and thus
Hughes-Winget Approximation
As also described in Rashid (1993), the stretching rate tensor and incremental rotation matrix in for the Hughes-Winget method are based on the spatial gradient of the displacement field evaluated at the mid-point of the time step The approximate stretching rate tensor can then be computed as and the incremental rotation matrix is approximated by where .
Volumetric Locking Correction
In ComputeFiniteStrain, is calculated in the computeStrain method, including a volumetric locking correction of where is the average value for the entire element. The strain increment and the rotation increment are calculated in computeQpStrain(). Once the strain increment is calculated, it is added to the total strain from . The total strain from must then be rotated using the rotation increment.

[]commentnote:Use of the Solid Mechanics QuasiStatic Physics Recommended
The Solid Mechanics Physics is designed to automatically determine and set the strain and stress divergence parameters correctly for the selected strain formulation. We recommend that users employ the Solid Mechanics Physics whenever possible to ensure consistency between the test function gradients and the strain formulation selected.
Although not recommended, it is possible to directly use the ComputeFiniteStrain material in the input file.
[./strain]
type = ComputeFiniteStrain
block = 0
displacements = 'disp_x disp_y disp_z'
[../]When directly using ComputeFiniteStrain in an input file as shown above, the StressDivergenceTensors kernel must be modified from the default by setting the parameter use_displaced_mesh = true. This setting is required to maintain consistency in the test function gradients and the strain formulation. For a complete discussion of the stress divergence kernel settings and the corresponding strain classes, see the section on Consistency Between Stress and Strain in the SolidMechanics module overview. In addition, be aware of the loading cycle limitations while using finite strains as outlined in the section Large Strain Closed Loop Loading Cycle.

# 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 `StructureAcousticInterface` interface kernel. The domain is 1D with 20m
# length. The fluid domain is on the right and the structural domain is on the left.
# Fluid end is subjected to a 250Hz sine wave with a single peak of amplitude unity.
# Structural domain is 4 times as dense as the fluid domain with all other material
# properties being the same. Fluid pressure is recorded at the midpoint in the fluid
# domain (i.e., at 15m). Structural stress is recorded at the midpoint in the structural
# domain (i.e., at 5m). The recorded pressure and stress amplitudes should match
# with theoretical values.
#
# Input parameters:
# Dimensions = 1
# Length = 20 meters
# Fluid speed of sound = 1500 m/s
# Fluid density = 1e-6 Giga kg/m^3
# Structural bulk modulus = 2.25 GPa
# Structural shear modulus = 0 GPa
# Structural density = 4e-6 Giga kg/m^3
# Fluid domain = true
# Fluid BC = single peak sine wave applied as a pressure on the fluid end
# Structural domain = true
# Structural BC = Neumann BC with value zero applied on the structural end.

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

# trial stress_yy = 2.1 and stress_zz = 3.0

# Then all three will be active, but there is linear-dependence.
# SimpleTester1 will turn off, since it is closest,

# then SimpleTester1 will be positive, so it will be turned back
# on, and then SimpleTester0 or SimpleTester2 will be turned off
# (a random choice will be made).
# If SimpleTester2 is turned
# off then algorithm returns to stress_zz=1=stress_yy, but then
# SimpleTester2 violates Kuhn-Tucker (f<0 and pm>0), so the algorithm
# will restart, and return to stress_zz=1=stress_yy, with internal0=2
# and internal1=1.1
# If SimpleTester0 is turned off then the algorithm will return to
# stress_zz=2, stress_yy=1, where f0>0. Once again, a random choice
# of turning off SimpleTester1 or SimpleTester2 can be made. Hence,

#
# Cavity Pressure Test
#
# This test is designed to compute an internal pressure based on
# p = n * R * T / V
# where
# p is the pressure
# n is the amount of material in the volume (moles)
# R is the universal gas constant
# T is the temperature
# V is the volume
#
# The mesh is composed of one block (1) with an interior cavity of volume 8.
# Block 2 sits in the cavity and has a volume of 1. Thus, the total
# initial volume is 7.
# The test adjusts n, T, and V in the following way:
# n => n0 + alpha * t
# T => T0 + beta * t
# V => V0 + gamma * t
# with
# alpha = n0
# beta = T0 / 2
# gamma = -(0.003322259...) * V0
# T0 = 240.54443866068704
# V0 = 7
# n0 = f(p0)
# p0 = 100
# R = 8.314472 J * K^(-1) * mol^(-1)
#
# So, n0 = p0 * V0 / R / T0 = 100 * 7 / 8.314472 / 240.544439
# = 0.35
#
# The parameters combined at t = 1 gives p = 301.
#
# This test sets the initial temperature to 500, but the CavityPressure
# is told that that initial temperature is T0. Thus, the final solution
# is unchanged.

#
# Cavity Pressure Test
#
# 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.

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

#
# Cavity Pressure Test
#
# This test is designed to compute an internal pressure based on
# p = n * R * / (V_cavity / T_cavity + V_add / T_add)
# where
# p is the pressure
# n is the amount of material in the volume (moles)
# R is the universal gas constant
# T_cavity is the temperature in the cavity
# T_add is the temperature of the additional volume
#
# The mesh is composed of one block (1) with an interior cavity of volume 8.
# Block 2 sits in the cavity and has a volume of 1. Thus, the total
# initial volume is 7. An additional volume of 2 is added.
#
# The test adjusts n, T, and V in the following way:
# n => n0 + alpha * t
# T => T0 + beta * t
# V => V_cavity0 + gamma * t + V_add
# with
# alpha = n0
# beta = T0 / 2
# gamma = -(0.003322259...) * V0
# T0 = 240.54443866068704
# V_cavity0 = 7
# V_add = 2
# T_add = 100
# n0 = f(p0)
# p0 = 100
# R = 8.314472 J * K^(-1) * mol^(-1)
#
# An additional volume of 2 with a temperature of 100.0 is included.
#
# So, n0 = p0 * (V_cavity / T_cavity + V_add / T_add) / R
# = 100 * (7 / 240.544439 + 2 / 100) / 8.314472
# = 0.59054
#
# The parameters combined at t = 1 gives p = 249.647.
#
# This test sets the initial temperature to 500, but the CavityPressure
# is told that that initial temperature is T0. Thus, the final solution
# is unchanged.

#
# 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.

# 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
