By extending Bueckner’s principle suited for a crack to a hole crack problem in infinite plate in tension,here,the original problem(the hole crack problem in infinite plate in tension) is divided into a homogeneous problem(the one without hole crack) subjected to remote loads and a hole crack problem in an unloaded body with applied tractions on the surfaces of hole and crack. Numerical results illustrate that the approach is very simple and effective for analyzing the hole crack problem in infinite plate in tension and by which a crack emanating from a triangle hole in infinite elastic plate in tension is analyzed in detail.The effect of hole geometry parameters on the stress intensity factors is revealed.It is found that a hole has a shielding and an amplifying effect on the stress intensity factors of crack emanating from the hole,and the shielding and amplifying effects varied with hole geometry parameters.
