The frictional hysteresis at relative motion within pre-sliding range in considered. The latter is characterized by elasto-plastic interaction on the micro-scale between two rubbing surfaces in contact that gives rise to nonlinear friction force in displacement showing the hysteresis characteristics. In the recent study, the damping characteristics of frictional hysteresis are analyzed. It is worth noting, that we exclude the additive viscous damping mechanisms and concentrate on pure hysteresis damping behavior to be described for friction modeling. We consider several advanced dynamic friction models, among Dahl, LuGre, GMS, 2SEP, and hysteresis-area-based one, to show the nonlinear damping ratio and convergence to the equilibrium state. Also, several related experimental observations from actuated motion with pre-sliding friction are provided.
