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

**Abstract:**

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.
