Detailed Description

CrystalPlasticityTwinningKalidindiUpdate uses the multiplicative decomposition of the deformation gradient, contributing shear due to twinning to the plastic velocity gradient via the parent class.

If using this class in combination with a dislocation slip model (the common case), make sure to provide that class with the material property of the total twin volume fraction. Not all slip classes are compatible with twinning.

◆ sortCrossSlipFamilies()

void CrystalPlasticityStressUpdateBase::sortCrossSlipFamilies ( )

inherited

A helper method to sort the slip systems of a crystal into cross slip families based on common slip directions.

This method determines if slip directions are parallel, and stores the index of the slip systems from getSlipSystems (the same index is used for the applied shear stress and the internal state variables) in a vector of vectors, where the outer vector separates the individual slip system families and the inner vector stories the indices of the slip systems within a single family. This vector of vectors can then be used in the inheriting classes to calculate cross slip interactions. The values of number_cross_slip_directions and number_cross_slip_planes must be set to use this sorting method.
