Description: Deformation of heterogeneous material containing internal interfaces or/and free surfaces is accompanied by collective vortex motion near such boundaries. Nevertheless, such fundamental factor as elastic vortex motion in material formed during dynamic loading still remains out of the discussion. The aim of this paper is to reveal the role of vortex displacements in contact interaction of heterogeneous coatings with hard counter-body by means of 3D computer simulation using movable cellular automata. The research is mainly focused on the role of vortex structures in the velocity field in elastic and non-elastic deformation of the coating. The peculiarities of the velocity vortex formation and propagation, as well as interaction with the structural elements are studied.
