A model of the process leading to formation of the third body elements at fracture of material in a dry friction contact zone was suggested. A variant of a plane element of the third body evolution was analyzed for the regime of an intensive shear action on its contact surfaces. A separated fragment can form an rolling element or remain to be a plane slipping element in dependence on a relation between normal pressure forces and shear forces in the contact zone. A criterion for twisting a plane element into a rolling element was obtained (within the framework of the plane elasticity)
