A New Approach to Predicting Interfacial Crack Growth

  • A new approach, called "β=0 approach" is presented for use in the prediction of interfacial crack growth. This approach is a kind of transformation. It transforms an oscillatory stress field to a nonoscillatory case by adjusting the elastic constants of the materials involved. The interface toughness locus is also changed according to the new material properties. It is shown that this approach will predict the exact same critical load as interfacial fracture mechanics does. Finally several examples are presented to show how to enforce β=0 while keeping the energy release rate unchanged.
