Abstract:
In this paper, the displacement field for the mode III interface crack between two materials is obtained by using the laser holographic interferometry. Through experimental data processing control parameters KIII, J of stress field intensity around crack tip are obtaied, and the applicable region of local solution is given. The continuity condition across the interface between two materials is studied. Rationality of the results is analysed. For contrast, specimen of homogeneous material was testedd and dat...
