A numerical Analysis for Cracks Emanating from a Quarter-Spherical Cavity on the edge of an Elastic Body

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 comer crack.In addition,it is found that the effect of boundaries parallel to the crack on the SIFs is obvious when.H/R≤3
