Elastoplastic Models to Describe Experimental Data on the Spallation Fracture under Impact of Plates / A. B. Kiselev and A. V. Mishchenko. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2015. № 6. P. 29-36 [Moscow Univ. Mech. Bulletin. Vol. 72, N 2, 2017. P. 135-143].

The processes of irreversible dynamic deformation and spallation fracture under plane impact of plates are numerically studied. 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.

Key words: elastoplasticity, damage parameters, dislocations, plane impact of plates, spallation fracture, TIS-1D software complex.
