Abstract
A combined elastic-viscous-plastic model is proposed for simulating deforma tion of heterogeneous media. The calculations are carried out by quasi-stat ic and dynamic methods in 2D (both for plane strain and plane stress) and 3 D formulations. The results of simulation of plastic strain localisation an d fracture in meso-volumes of ceramics with pseudo-plastic matrix and polyc rystalline materials are presented and discussed.
