Coupling Effects of Interfacial Diffusion and Sliding on Electro-Mechanical Behaviors of Laminated Plates With Embedded Piezoelectric Layers

The time-dependent responses of an angle-ply laminated plate with an embedded piezoelectric layer in cylindrical bending is investigated based on the state-space method. Both the interfacial diffusion and sliding are considered to simulate the interlaminar imperfect bonding. Besides, a matrix reduction technique is adopted to establish the global transfer relations of the elastic variables between the piezoelectric layer and the elastic strip. Then, the exact solutions are obtained by solving a set of differential equations with respect to time. The numerical investigation indicates that the coupling effects of the interfacial diffusion and sliding should be considered carefully for the analysis of an imperfectly laminated structures.
