Abstract
In order to understand the fracture phenomenon of an internal crack subjected to dynamic impact loading, a subsurface crack contained in a half-space is studied. The realistic impact loading is simulated by a Sine function with a duration period. The solutions are determined by linear superposition of the Green function obtained by Tsai and Ma [1]. The exact closed form solutions of stress intensity factor histories are obtained. These solutions are valid for the time interval from initial loading until the first wave scattered at the crack tip returns to the crack tip after being reflected by the free boundary. The probable crack propagation direction is also predicted from the fracture criteria of maximum circumferential tensile stress.
