Solution of basic boundary problems for 2-dimentional  equtions of plasticity

For the system of two-dimensional plasticity equations with the help of the conservation laws the boundary problems are solved. It's finding the solutions of some concrete boundary problems. By the using of the symmetry transformations, from the wellknown Prandtle's solution we deduce some new solutions, describing the pressing of layer between two rugged slabs. Also, some new properties of the characteristics of plane plasticity are shown.
