Abstract
The possibility of using the optical method of caustics in analysis of the interfacial crack is investigated in this study. The explicit full field solution for applying arbitrary point loadings on interfacial crack faces is used in analyzing this problem. The size of the yielding zone and the pattern of the caustics in the oscillatory and singular regions are studied by numerical simulation. The oscillatory region is found to be extremely small for most material combinations. The size of the yielding zone predicted by the Von Mises criteria is significantly larger than that of the oscillatory region. It is also very interesting to find that the patterns of the caustics inside the oscillatory region are similar to that in the singular field. © 1995.
