Description of evolution of contact and free boundaries is one of problems in numerical simulation of nonstationary high-rate processes. The complex Eulerian-Lagrangian calculation techniques are the most promising for such a description since the purely Eulerian methods require a large number of calculation points to obtain a required approximation, at purely Lagrangian approach the calculation errors increase quickly for large grid deformations. Definition of boundaries is a part of the general problem of solution construction of the initial boundary value problem in continuum mechanics and becomes of current concern for modelling pulse processes in metals. This is due to that in a given class of processes and media inside the continuity regions new free surfaces, such as cracks and fragment boundaries, can appear. 2b1af7f3a8
