Abstract

The subloading-friction model with a smooth elastic-plastic sliding transition is extended so as to describe the reduction from the static to kinetic friction and the recovery of static friction. The reduction is formulated as the plastic softening due to the separations of the adhesions of surface asperities induced by the sliding and the recovery is formulated as the creep hardening due to the reconstructions of the adhesions of surface asperities during the elapse of time under a quite high actual contact pressure between edges of asperities.
