PlasticSpatialVelocityGradient

Source: models/solid_mechanics/crystal_plasticity/PlasticSpatialVelocityGradient.py

Caclulates the plastic spatial velocity gradient as \(l^p = \sum_{i=1}^{n_{slip}} \dot{\gamma}_i Q \left(d_i \otimes n_i \right) Q^T\) with \(l^p\) the plastic spatial velocity gradient, \(\dot{\gamma}_i\) the slip rate on the ith slip system, \(Q\) the orientation, \(d_i\) the slip system direction, and \(n_i\) the slip system normal.
