N2 - Based on the dynamic theory of linear piezoelectricity, we investigated the scattering of horizontally polarized shear waves from a single piezoelectric fiber partially bonded to an elastic matrix. The debonding is assumed to be curved interface cracks with non-contacting faces. The wave function expansion method is employed to reduce the problem to the solution of a pair of dual series equations. The solution of the dual series equations is then expressed in terms of a singular integral equation, introducing a dislocation density function. Numerical results for P7-epoxy and N8-epoxy composites are obtained. The effects of frequency, crack angles, and distributions on the dynamic stress intensity factor, dynamic energy release rate, scattering cross section, and electrical signal are discussed in detail.
