review text: Two-dimensional plastic waves of the quasi rate independent viscoplastic materials are considered. The mathematical model of the problem is formulated using the nonlinear evolution equation for plastic stretching. Wave equations and momentum equations are stated with initial and boundary conditions. The main limitation in the presented analysis is the assumption that the plastic waves do not change their direction during propagation. It is valid only when plastic strains are small and comparable with elastic ones. Results of the numerical simulation for symmetric and non-symmetric loadings are presented. These results are comparable with those obtained experimentally. In this paper also the direction of the prospective investigation in the problem is mentioned.
