Abstract

We investigate the sliding dynamics of atomic-scale friction at different time scales. Depending on the dynamic inertia and sliding velocity of a cantilever, different dynamic behaviors are observed from both conventional molecular dynamics (MD) simulation and temporally hybrid molecular simulation methods. The mechanism of friction dissipation is also investigated. For either smooth sliding or stick–slip, a non-zero work of friction is obtained, while surface forces are no longer conservative.
