On thermodynamics of crystal plasticity
Scripta Materialia, 2006Abstract It is argued in this paper that there are three distinctive physical situations in which the continuum descriptions of crystal plasticity are conceptually different. They are determined by the properties of the random field of dislocation density. One of the cases corresponds to conventional plasticity theory.

When crystals are strained above a certain limit, they cease behaving like elastic solids and become plastic. Plastic deformation is an irreversible, isovolume process, which results in a permanent shear strain after the shear stress that caused it has been removed. Hydrostatic pressure alone does not produce plastic deformation.

Crystal-Plasticity Fundamentals
2009Abstract This article presents the Schmid's law that describes the response of crystal structures to loading. It describes the Taylor model to calculate the uniaxial yield stress of an isotropic face-centered cubic aggregate in terms of critical resolved shear stress. The article discusses the stress-based approach of the Bishop and Hill
