Elastoplastic models to describe experimental data on the spallation fracture under impact of plates

A study of numerical investigation of irreversible dynamic deforming and spallation fracture under plane impact of plates is given. The following two models for the behavior of the materials of the plates are used: a model of a damageable elastoplastic medium and a dislocation model. The computations were performed with the use of the TIS-1D software complex based on the method of separation into physical processes, the finite volume method, and moving Eulerian grids.
