Abstract

An algorithm of a numerical solution to a static problem, modeling large displasements and deformation of bodies, produced of elastoplastic materials, is suggested. The finite element method and the method of continuation with respect to the best parameter are used. After discretization the problem transformed to solution of initial-value problem for a system of ordinary differential equations.
