OrientationRate

Source: models/solid_mechanics/crystal_plasticity/OrientationRate.py

Defines the rate of the crystal orientations as a spin given by \(\Omega^e = w - w^p - \varepsilon d^p + d^p \varepsilon\) where \(\Omega^e = \dot{Q} Q^T\), \(Q\) is the orientation, \(w\) is the vorticity, \(w^p\) is the plastic vorticity, \(d^p\) is the plastic deformation rate, and \(\varepsilon\) is the elastic stretch.
