Abstract

Ultrasonic fractography technique was utilized to study dyamic crack response to mode II shear wave. In this study, dependence of the crack response on the dynamic stress intensity factor Ktd, was studied quantitatively. Maximum modulation angle ξ and fracture velocity Vf were evaluated. Values of Ktd were obtained from diameters of caustics which were taken by high-speed photography. The result showed that Ktd increases with increasing Vf. Values of ξ decreases with increasing Ktd at constant ultrasonic amplitude.
