摘要：

An elastic half-plane was subjected to a uniform pressure over part of its surface. A normal edge crack is assumed to lie at the edge of the loaded region. The effect of Coulomb friction between the crack faces was considered, and the various possibilities involving stick and slip regions along the crack was examined. Stress intensity factors were obtained. It is shown that there are no residual internal stresses present after a load cycle, so that there is no possibility of shakedown. Also, the steady-state range of stress intensity factor is the same as that induced in the first cycle.
