Description:Stiffness tensor for material
Compute Elasticity Tensor CP
Compute an elasticity tensor for crystal plasticity.
Description
The material ComputeElasticityTensorCP is used to create an elasticity tensor for crystal plasticity simulations. This material builds an orthotropic elasticity tensor using the fill_method symmetric9 from ComputeElasticityTensor. ComputeElasticityTensorCP rotates the elasticity tensor both during the initial setup step, if Euler angles are provided, and at the start of each timestep.
warningwarning:Crystal Plasticity Simulations use Active Rotation
The rotation matrix used in this class,ComputeElasticityTensorCP, is the transpose of the rotation matrix created from the Bunge Euler angles in the base class, ComputeElasticityTensor. This difference in the rotation matrix is because of the active rotation convention used in crystal plasticity simulations.
The fill method symmetric9 is appropriate for materials with three orthotropic planes of symmetry (Malvern, 1969), and is used for simulations of anisotropic materials such as cubic crystals. The engineering elasticity tensor notation for an orthotropic material is given in Eq. (1): (1)
Rotation Tensor Conventions
The Euler angle convention used in ComputeElasticityTensorCP is the -- (3-1-3) convention. The Euler angles arguments are expected in degrees, not radians, and are denoted as , , and , corresponding to the axis rotations. The rotation tensor, , is calculated from the current Euler angles at each timestep as shown in Eq. (2). (2) The elasticity tensor is then rotated with Eq. (3) (3) at the beginning of each material timestep calculation.
The crystal plasticity materials, including ComputeElasticityTensorCP employ an active rotation: the crystal system is rotated into the sample (loading) coordinate system. Generally the Bunge Euler angles are used to describe a passive rotation: rotating the sample coordinate system into the crystal coordinate system. As a result, the rotation tensor applied is the transpose of the rotation tensor given in Eq. (2) as noted in Eq. (3).
As in the base class ComputeElasticityTensor, ComputeElasticityTensorCP can also accept the rotation matrix, given as a series of nine entries. As with the Euler angle input parameter values, note that this crystal plasticity class uses the "passive" rotation convention.

- 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 is designed to test the correct application of the Euler angle
# rotations to the elasticity tensor. The test uses values for the nine C_ijkl
# entries that correspond to the engineering notation placement:
# e.g. C11 = 11e3, c12 = 12e3, c13 = 13e3, c22 = 22e3 ..... c66 = 66e3
#
# A rotation of (0, 90, 0) is applied to the 1x1x1 cube, such that the values of
# c12 and c13 switch, c22 and c33 switch, and c55 and c66 switch. Postprocessors
# are used to verify this switch (made simple with the value convention above)
# and to verify that the unrotated components along the x-axis remain constant.

# This test is designed to test the correct application of the Euler angle
# rotations to the elasticity tensor. The test uses values for the nine C_ijkl
# entries that correspond to the engineering notation placement:
# e.g. C11 = 11e3, c12 = 12e3, c13 = 13e3, c22 = 22e3 ..... c66 = 66e3
#
# A rotation of (0, 90, 0) is applied to the 1x1x1 cube, such that the values of
# c12 and c13 switch, c22 and c33 switch, and c55 and c66 switch. Postprocessors
# are used to verify this switch (made simple with the value convention above)
# and to verify that the unrotated components along the x-axis remain constant.

# This test is designed to test the correct application of the Euler angle
# rotations to the elasticity tensor. The test uses values for the nine C_ijkl
# entries that correspond to the engineering notation placement:
# e.g. C11 = 11e3, c12 = 12e3, c13 = 13e3, c22 = 22e3 ..... c66 = 66e3
#
# A rotation of (0, 90, 0) is applied to the 1x1x1 cube, such that the values of
# c12 and c13 switch, c22 and c33 switch, and c55 and c66 switch. Postprocessors
# are used to verify this switch (made simple with the value convention above)
# and to verify that the unrotated components along the x-axis remain constant.
