摘要：

An effective method is represented, allowing: (a) to construct analytically fields of plastic deformation with gradients within the local volumes of an arbitrary plastically deforming solid; (b) to define corresponding distributions of stress tensor components; (c) to simulate the process of localization of plastic deformation (LPD). The original analytical solutions for stress fields, from the sites of LPD in the form of circle, ellipse, square, and drawn right-angled quadrangle, oriented perpendicular to tensile axis are represented. A mesomechanical model of LPD development in polycrystals is offered, taking work hardening, a number of sliding systems and edge effects into account. (C) 1998 Elsevier Science B.V.
