The paper presents results of numerical calculation of displacement of a geomedium block along the inclined plain in the presence of a round friction spot. Modeling reveals differences in processes for the elastic and elastoplastic media. In the elastic medium, displacement is symmetric from the spot edges. In the elastoplastic medium, gradual slip and displacement within the friction spot proceed from the edge subjected to the pushing force. Maximum increase in plastic strain is from the edge subjected to the pulling force. The calculations are performed in a 3D statement within the elastic and elastoplastic Drucker-Prager model with the nonassociated flow rule.
