AssociativeKinematicPlasticHardening

Source: models/solid_mechanics/plasticity/AssociativeKinematicPlasticHardening.py

Map the flow rate (i.e., the consistency parameter in the KKT conditions) to the rate of internal variables. This object calculates the rate of kinematic plastic strain following associative flow rule, i.e. \(\dot{\boldsymbol{K}}_p = - \dot{\gamma} \frac{\partial f}{\partial \boldsymbol{X}}\), where \(\dot{\boldsymbol{K}}_p\) is the kinematic plastic strain, \(\dot{\gamma}\) is the flow rate, \(f\) is the yield function, and \(\boldsymbol{X}\) is the kinematic hardening.
