摘要：
The scattering of Love waves by an interface crack between a piezoelectric layer and an elas-tic substrate is investigated by using the integral transform and singular integral equation techniques.The dy-namic stress intensity factors of the left and the right crack tips are determined.It is found from numericalcalculation that the dynamic response of the system depends significantly on the crack configuration,the ma-terial combination and the propagating direction of the incident wave.It is expected that specifying an appro-priate material combination may retard the growth of the crack for a certain crack configuration.
