主　　题：interfacial crack crack growth β=0 approach critical load 

摘      要：A new approach, called β=0 approach is presented for use in the prediction ofinlerfocial crack growth. This approach is a kind of transformation. It transforms anoscillatory stress field to a nonoscillatory case by adjusting the elastic constants of thematerials involved. The interface toughness locus is also changed according to the newmaterial properties. It is shown that this approach will predict the exact same criticalload as interfacial fracture mechanics does. Finally several examples are presented toshow how to enforce β=0 while keeping the energy release rate unchanged.
