Abstracts:
The problem Koshi about distribution of the zones of a plastic condition to the boundless environment from the border of a convex surface on which there are an operate normal pressure,the tangents of an effort and the set speeds of the movings is considered. In case of full plasticity and linear dependence of a condition of fluidity on the average pressure the system of the quasistatic equations of the ideal plasticity describing the intense-deformed condition of the environment, is hyperbolic. At the numerical decision of this system the difference scheme to the hyperbolic systems of the preservation laws is applied.
