摘要

This note is specifically concerned with cracks emanating from a quarter-spherical cavity on the edge in an elastic body (see Fig. 1) by using finite element method. The numerical results show that the existence of the cavity has a shielding effect of the corner crack. In addition, it is found that the effect of boundaries parallel to the crack on the SIFs is obvious when.H/R≤3
