<CRYSTAL_KINEMATIC>#
Description#
Because the crystal potential models takes into account the strains on
the individual slip planes, kinematic hardening represents a linear
measure of a slip offset distance
The internal variables x0
and C
parameters having the dimensions of a stress. Trick: a large negative
offset x0
might be used to model unidirectional slip, provided
that the same positive offset is added to the corresponding isotropic
hardening.
These hardening laws will apply uniquely for the monocrystal potentials. Permissible crystalline kinematic types are with their additional parameters are
