Cracking of a Homogeneous Half Plane Due to Sliding Contact

Abstract

In this report the initiation and subcritical growth of surface cracks in homogeneous materials due to sliding contact are considered The load is applied through a rigid stamp with an arbitrary profile. The problem is formulated and solved under the assumptions of plane elasticity and Coulomb friction. The stress state on the surface of the half plane is analyzed in the absence of any cracks in order to determine the crack initiation force and angle. A surface crack is then introduced and the resulting coupled crack/contact problem is investigated. Extensive results are presented regarding mostly the mixed mode stress intensity factors which constitute the main driving force for the subcritically growing cracks.
