Abstract

Abstract This note is specifically concerned with cracks emanating from a surface semi-spherical cavity in an infinite body (see Fig. 1 ) by using the boundary element software FRANC3D developed by a fracture mechanics investigation group of Cornell University. The numerical results can reveal the effect of the geometry of the surface cavity on the stress intensity factors.
