Deformations and stresses with and without microslip

Abstract: "Kinematical definitions of deformations with and without microslip are presented. Transformation properties for such deformations are shown to follow directly from their definitions, and Burgers vector is related to the deformation without microslip. A limit procedure provides a concept of stress without microslip and leads to a natural concept of elastic response. Various decompositions of local deformation into elastic and plastic parts proposed in the literature are shown to be compatible with this kinematical setting."
