A high friction coefficient is first observed as a sliding between bodies commences, which is called the static-friction. Then, the friction coefficient decreases approaching the lowest stationary value, which is called the kinetic-friction. Thereafter, if the sliding stops for a while and then it starts again, the friction coefficient recovers and a similar behavior as that in the first sliding is reproduced. These facts are fundamental characteristics in the friction phenomenon, which have been widely recognized for a long time. In this article the subloading-surface friction model with a smooth elastic-plastic sliding transition is extended so as to describe these facts by formulating the rate-dependent hardening/softening rule of sliding-yield surface adequately.
