“…The presented computer modeling results are in good agreement with the experimental investigation [4,5]. This is also true for macroscopic studies, when modeling results can be directly compared with experimental measurements, as well as for the results obtained within the atomic and mesoscale description of the behavior of the modeled medium.…”

“…Among the effective methods for highperformance treatment of functional surfaces of precision parts is a method of surface plastic deformation, which is called burnishing [25]. The burnishing process results not only in a significant reduction of roughness of the surface layer up to 100 or less nanometers [4,5] but also in an increase of its strength properties, wear and fatigue resistance. It has been found that the change in properties of burnished surfaces is associated with structural changes of a thin surface layer, which, in terms of physical mesomechanics [6], can be taken as an independent system of nanoclusters with specific mechanisms of plastic flow being nondislocational in nature.…”

“…In this connection numerical modeling techniques can be complementary to the experimental studies. The present paper employs computer modeling to reproduce loading details when treating the surface layer by nanostructuring burnishing [4,5,7]. The investigations are performed not only on the macroscale (conventional approach, see, for example, [7,8]) but also on the atomic scale and mesoscale.…”

The operating characteristics of machine parts and units are defined in many respects by the physical and mechanical properties of their surface layers. Unfortunately, it is still not quite clear what parameters and mechanisms are responsible for one or another modification of surface layer properties. In this context, computer modeling techniques can be a useful tool in studying the variation of surface properties in contact interaction and run-in. Of fundamental importance is the possibility to consider the processes occurring on nanoscales and scales of individual atoms. In the work, loading conditions in plastic surface deformation was reproduced on the macroscale (traditional approach), atomic scale, and mesoscale by computer modeling with the finite element method, movable cellular automata method, and molecular dynamics method. The modeling results are in good qualitative agreement with data of experimental measurements.
