Elastoplastic problems in the uniaxially strained state approximation. Analytical and numerical solutions

A detailed study of a shock-wave structure and an unloading wave for elastoplastic problems in the one-dimensional deformed state approximation is given. A brief description of a numerical algorithm is also given. The verification of the TIS software complex is discussed for one-dimensional plane problems. This complex is based on the method of separation into physical processes and on the finite volume method using moving Eulerian grids.
