| Abstract: | 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. |
