Abstract
The equations of caustics for dynamically extending curvilinear interf ace cracks are derived where optical isotropy and anisotropy of the ma terial have been considered, respectively. The equations have been obt ained by applying the method of generalized complex potentials. Moreov er, an algorithm for the determination of stress intensity factors fro m experimentally obtained caustics is presented for the case of dynami c crack extension.
