Abstract

Interfacial crack growth is inherently mixed mode in nature and mode-mixity must be defined clearly in order to characterize it. Mode   and mode   strain energy release rates for an interfacial crack in bimaterial system were analytically derived by the virtual crack closure technique. It is shown that the energy release rate for mode   and mode   do not converge due to the presence of violent oscillatory near tip behavior. However, the total energy release rate is well-defined.
