Abstract

Abstract

The conservation law of J integral in two-media with a crack paralleling to the interface of the two media was firstly proved by analytical and numerical finite element method.Then a schedule model was established that an interface crack is inserted in four media.According to the J-integral conservation law on multi-media,the energy release ratio of-type crack was considered to be conservation when the middle medium layers are very thin.And the conservation law was also convinced by numerical method.By means of the dimension analysis on the model,the asymptotic results and formula calculating the energy release ratio and complex stress intensity factor are presented.
- multi-materials,
