The mathematical model of the contact of the faces of the interfacial crack outcoming from the angular point of the broken interface

Abstract

The model of the interfacial crack outcoming from the angular point of the broken interface of two different homogeneous isotropic materials has been developed. The model assumes the existence of a near the tip of the crack small-scale contact region of the faces interacting according to the law of dry friction. The equations for the determination of the length of the contact zone and stress singularity index near the crack tip and an expression for the contact stress were obtained.
