Using the integral transform method, the scattering problem of Love wave and plane wave to the interfacial crack between a piezoelectric layer and a homogeneouse substract is investigated in this paper. The dynamic stress intensity factors under mode I, II and III of the left and the right crack tip are deduced. The numerical results show that the maximal value and the oscillation of the dynamic stress intensity factors increase with the increasing of the crack size, and that the different material combiantions may promote or impede the growth of the crack. Moreover, the dynamic stress intensity factors of plane wave scattering problem is evidently influenced by the incident direction of the incident wave.
