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