Specific Features of Contact of the Faces of an Edge Crack Under Moving Hertzian Loads

We consider the contact problem of the theory of elasticity for a half plane containing an edge oblique crack whose faces are in contact (with friction) under the action of a Hertzian contact load unidirectionally moving along the edge of the half plane. We present the maps of contact of the crack faces and compute stress intensity factors for the combinations of parameters typical of rolling contact interaction (the coefficients of friction between the crack faces and rolling bodies, crack orientation, and crack length).
