Abstract
During a load cycle, an existing crack may partially close causing the fractured surfaces to make contact. This would of course influence the stress field. The frictional forces arising at the contact surface could be expected to influence the direction of crack propagation. Contact problems in fracture mechanics have been studied by some authors. Aksogan presents a solution to the elastic problem of a closing Griffith crack. Paris and Tada studies a closing elastic single edge crack loaded in mode I. Newman studies the effects of closing cracks in fatigue crack propagation. Erdogan and Gupta studies contact and crack problems of elastic wedges. All of these solutions are restricted to specific types of geometries and loadings and do not include friction. This chapter presents a unified approach to elastic contact problems taking frictional effects into account.
