The 3-D bodies nonlinear deformation and damage processes by highvelocity impact collisions

Three-dimensional high velocity impact problems of the deforming arbitrary shape bodies are numerically simulated. Determining relations include a visco-elastoplastic behavior of the damaged materials with the large strains. FEM with the optimal (rational) finite difference schemes in the time domain are used. The basic aspects of the mathematical simulation and solutions of the some important for the atomic power stations safety problems are represented.
