Many of the present and potential applications of graded materials involve contact problems. These are mostly load transfer components in elastic solids in the presence of friction. From a viewpoint of failure mechanics an important aspect of contact problems is surface cracking which is caused by friction forces. In this study the general crack/contact problem for a graded medium loaded by a sliding rigid stamp is considered. With applications to initiation and propagation of surface cracks in mind, the in-plane stress components on the surface of the graded medium, and the stress intensity factors at the tip of a surface crack are evaluated. The singular behavior of the coupled crack/contact problem is then examined, some examples are considered and sample results are given.
