Transient Response of Cracks Emanated from a Circular Hole under Impact Loading

Abstract

The transient stress field around a finite crack emanated from a circular hole is obtained using integral transforms method. The normal
and shear tractions applied to cracks surface. Firstly, the dynamic stress concentration factor around the circular hole without crack is
calculated and secondly, the concentration stress around the hole is applied to the crack surface and the stress filed in the crack tip and
dynamic stress intensity factor is obtained. Because of the normal and shear stress, the mode I and II of fracture happen. Finally, the results
are compared with previous studies.
