## Abstract

Recent studies show interest in materials with asymmetric friction forces. We investigate terminal motion of a solid body with circular contact area. We assume that friction forces are asymmetric orthotropic. Two cases of pressure distribution are analyzed: Hertz and Boussinesq laws. Equations for friction force and moment are formulated and solved for these cases. Numer- ical results show significant impact of the asymmetry of friction on the motion. Our results can be used for more accurate prediction of contact behavior of bodies made from new materials with asymmetric surface textures.
