摘要：

Parallel molecular dynamics simulations of nanoindentation followed by nanoscratching were conducted on an fcc silver (100) surface using a diamond indenter. The simulations were performed using three different orientations of the indenter. For each orientation, simulations were performed for an indentation depth of 5 Angstrom and scratching length of 210 Angstrom. The damage on the substrate is investigated and the coefficient of friction calculated for all the three cases. The results show few sub-surface defects underneath the scratch groove, pile-up around the groove which is orientation dependent and that the friction coefficient varies from similar to0.37 to similar to0.57 depending on the tip orientation.
