| Summary: | Title screen The processes at various scale levels in the contact area of interacting objects under high-energy action will be examined from the viewpoint of mesomechanics. Modeling of contact area at atomic- and meso-scale levels was carried out on the base of discrete computational approach (method of particles). Molecular dynamic method was used at the micro-scale level; movable cellular automata method—at the meso-scale level. The gradient of velocity in areas near the surface leads to formation of low density and fragmented areas. This effect is accompanied by the failure of crystal lattice stability and intensive mixing process at the atomic level. The mechanisms of mass transfer in contact area were discussed. The results allow us to explain a host of experimental data of mechanochemistry such as phase formation at friction surface, alloy formation due to contact interaction under “pressure + shear” loading conditions.
