A model is constructed to analyze the effects of a concentrated contact on a layer that is perfectly bonded to an elastic half space, except for a debond region, which is analyzed as a frictional interfacial crack. The crack is assumed not to open and the growth is governed by a mode II stress intensity factor that is retarded by interfacial friction. This model may be used to study the fracture of hard coatings at the asperity scale where the failure is caused by loss of adhesion at the interface.
