摘要：

With the advent of large-scale parallel computers in the past decade, it has become possible to study the microphysics of complex nonlinear many-body systems at scales approaching the mesoscale. One of the areas where nonequilibrium deformation arises is that of dry sliding friction between ductile metals. We discuss the results of atomistic simulation studies of sliding friction in the velocity range 10 to 10(3) m/s in the high-pressure regime of 5 to 15 GPa for Ta/Al and Cu/Ag tribopairs. We discuss the velocity dependence and the near interface deformation seen in these simulations.
