초록

In this study, the effect of downward inclined interface about interfacial crack of bimaterials are discussed. The fracture parameter are analyzed by finite element method of the ANSYS. The energy release rates, displacement jump and stress distribution were analyzed as the gradient variation of inclined interfaces. As a results, in case of positive shear displacement was applied, the energy release rates not varied with gradient of inclined interface increasing. However in case of negative shear displacement was applied, the energy release rates decreased with gradient of inclined interface increasing. Due to the inclined interface contact, the shielding effect relatively increased as the gradient of inclined interface was increased.
