Compute Incremental Strain
Compute a strain increment and rotation increment for small strains.
Description
The material ComputeIncrementalStrain is designed for linear elasticity problems formulated within an incremental framework. As with ComputeSmallStrain, this material is useful for verifying material models with hand calculations because of the simplified strain calculations. As in the small strain material, the incremental small strain class assumes the gradient of displacement with respect to position is much smaller than unity, and the squared displacement gradient term is neglected in the small strain definition to give: As the class name suggests, ComputeIncrementalStrain is an incremental formulation. The stress increment is calculated from the current strain increment at each time step. In this class, the rotation tensor is defined to be the rank-2 Identity tensor: no rotations are allowed in the model. Stateful properties, including strain_old and stress_old, are stored. This incremental small strain material is useful as a component of verifying more complex finite incremental strain-stress calculations.

[]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.

- 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.

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 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

#
# In this test, the specimen is free of external stress (sigma = 0) so the creep deformation only derives from
# the eigenstrain. The total strain to be expected is:
# epsilon = alpha * (1 + t / eta)
# Both the stress and the elastic strain are 0.

# ---------------------------------------------------------------------------
# This test is designed to verify the variable elasticity tensor functionality in the
# ComputeFiniteStrainElasticStress 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 ComputeIncrementalStrain. 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.
