摘要

Each of the above crack surface deformation profiles leads to a different pattern of crack-closure when the specimen is unloaded. In the cases of Lo-to-Hi loading and single overload, a considerable amount of crack-surface blunting occurs at the instant when the applied load is stepped up. This blunting precludes the possibility of crack-closure behind the location of this blunting in the subsequent load cycling (in the cases of Lo-to-Hi and single overload). Thus in these two cases of loading, immediately after the step-up in load level takes place, crack closure occurs only in the small area adjacent to the current crack-tip.
