This brief deals with crack(s) emanating from a hole in infinite plate subjected to uniform internal pressure. Such a crack problem is called a hole crack problem for short. By using a hybrid displacement discontinuity method (a boundary element method) proposed recently by Yan, three hole crack problems (an elliptical hole crack problem, a rhombus hole crack problem, and a triangle hole crack problem) in infinite plate subjected to uniform internal pressure are analyzed in detail. By changing hole geometry form and hole geometry parameters and by comparing the stress intensity factors (SIFs) of the hole crack problem with those of the center crack problem, the effect of the hole geometry form and hole geometry parameters on the SIFs is revealed. It is found that a hole has a shielding and an amplifying effect on the SIFs of crack(s) emanating from the hole. The shielding and amplifying effects are varied with hole geometry form and hole geometry parameters.
