| Abstract: | The problems of an interfacial crack with the crack tip normal to interface are investigated by experiment. High-resolution moire interferometry methods are employed to get displacement fields surrounding cracks. The order of singularity of displacement faction of angular displacement and stress intensity factor are determined from experimental results and it also be compared and discussed with some theoretical results. |
