Crystal hardening and the issue of uniqueness (Q1196487)

As a contribution to the discussion on uniqueness of the plastic slipping mode of crystals, we consider the elastic plastic uniform response to mixed, monotonic, and uniform loading conditions, of a finitely strained single crystal obeying the Schmid flow criterion; such conditions are dealt with, for instance, Taylor or other rate independent models for the plasticity of aggregates, as well as finite element methods.
