Abstract

A new hybrid atomistic-coarse-grained (HACG) treatment of reversible processes in multiple-scale systems involving fluid-solid interfaces was tested using Monte Carlo simulations. In the transition region the system exhibited a hysteresis loop whose breadth depends strongly on the thermodynamic state. Hysteresis is exacerbated by decreasing the temperature or increasing the load or film-substrate coupling constant. It was found that the elastic response of the remote regions of the substrate have a significant impact on the static friction profile.
