摘要：

Digital image processing was used to obtain the deformation fields around a propagating crack tip from photographic films recorded by a high-speed Cranz-Schardin camera. The in-plane displacements and strains determined from the process were then used to compute the dynamic stress intensity factor and the remote stress component parallel to the crack face. K dominance is discussed using the experimental data. Surface roughness of the fractured surface is also examined.
