Summary:Title screen
The paper reports the molecular dynamics simulation results on the behavior of acopper crystallite in local frictional contact. The crystallite has a perfect defect-free structureand contains a high-angle grain boundary of type ?5. The influence of the initial structure onthe specimen behavior under loading was analyzed. It is shown that nanoblocks are formed inthe subsurface layer. The atomic mechanism of nanofragmentation was studied. A detailedanalysis of atomic displacements in the blocks showed that the displacements are rotational.Calculations revealed that the misorientation angle of formed nanoblocks along differentdirections does not exceed 2 degrees.
