Abstract

Using large-scale molecular-dynamics simulations in two dimensions, we have observed interesting dislocation generation and dynamics at the interface between two smooth metallic surfaces. sliding relative to one another. The early-time behavior is related to later-time nanocrystalline structure at the interface whose formation is related to velocity-weakening in the coefficient of friction. We discuss the differences between frictional dislocation behavior in two and three dimensions.
