We study the dependence of the stress intensity factors in a body containing an edge arbitrarily oriented crack on the radius R of rounding of the edges in the base of a rider pressed with unilateral friction to the damaged body near the crack mouth. Within the framework of the two-dimensional problem, this body is modeled by an elastic half plane with edge cut and the action of the rider is replaced...
We propose an analytical model for investigation of the processes of fracture of a near-surface layer of bodies in the case of their unidirectional rolling under conditions of limit lubrication. The step-by-step calculation of trajectories of propagation of fatigue cracks using the criteria of local fracture in a complicated stressed state and with regard for the specific features of loading in a...
