“…Current research related to this issue offer various computational mesh adaptive algorithms [1][2][3]. Contact problems are solved using different numerical approaches [4][5][6]: Lagrange multiplier method, penalty and regularization method, quadratic programming, modifications of Newton method, Schwarz decomposition method, pseudo-medium, and others. Multiple algorithms modify the mesh only in two-dimensional case [7].…”

The paper presents results of applying approach to simulation of contact surfaces fracture under high velocity interaction of solid bodies. The algorithm of erosion -the algorithm of elements removing, of new surface building and of mass distribution after elements fracture at contact boundaries is consider. The results of coordinated experimental and numerical studies of fracture of materials under impact are given. Authors own finite element computer software program EFES, allowing to simulate a three-dimensional setting behavior of complex structures under dynamic loads, has been used for the calculations.
