Due to the stress concentration effect around the hole, cracks are likely to initiate at the hole under the action of fatigue loading. This paper is specifically concerned with cracks emanating from a surface semi-spherical cavity in a finite body by using the boundary element software FRANC3D developed by a fracture mechanics investigation group of Cor-nell University. The numerical results can reveal the effect of the geometry of the surface cavity on the stress intensity factors.
