In the paper the method of molecular dynamics is used to investigate the features of structure transformation, which are taking place during the process of surface treatment. The force field of a cylindrical shape was used to imitate the motion with constant velocity of hard indenter. The following parameters of tasks were varied: the radius of indenter, initial immersion depths, surface roughness, number of passes and the initial position of the indenter. Calculations were performed for the pure crystallites of copper and iron. According to the modeling the treatment of the surface layer can leads to formation of numerous structural defects, which can provide effect of nano-fragmentation of material near the surface. A comparison of surface topography before and after treatment was analyzed also. Results of our study are in good agreement with experimental data.
