000014259 520__ $$2eng$$aThis article presents a theoretical model of the coupled dynamic behaviour of a layered piezoelectric structure under inplane harmonic loads with the transverse inertia and debonding of the piezoelectric layer considered. The dynamic behaviour is studied to evaluate the dynamic load transfer from the substrate to the surface-bonded layer. The dynamic strain ratio and wave field under different loading frequencies and material combinations are obtained by using the Fourier transform and solving the appropriate singular integral equations using Chebyshev polynomials. This model is validated by comparing with the corresponding FEM results. The interfacial debonding has a significant influence on the wave propagation in the structure, and its effects on surface stress are studied, which can be used to detect the debonding position under proper frequencies.
