“…Substituting these solutions into equation 5, we can easily obtain the mid-plane strains and curvatures of the piezoelectric layer at o. Thus, we can obtain the relevant forces and moments of the piezoelectric layer in terms of equation (4). In a similar manner, we can also obtain the curvatures and moments of the elastic plate with one edge clamped and others edges free.…”

Since the delamination induced failure of a laminated smart structure always occurs under the action of mechanical and electrical fields, a generalized two-dimensional model for a piezoelectric/elastic laminate is established in order to analyze the effect of an applied electric field on its delamination. First, based on the double Fourier series method, a general analytical solution of the mid-plane displacement is derived for any boundary condition. Furthermore, the energy release rate is employed to study the influence of the applied electric field and mechanical loading on the fracture characteristics of the piezoelectric/elastic laminate. The energy release rates for modes I and II fracture behavior of the PZT/elastic laminates are calculated in detail. Such calculations indicate that it is feasible to choose not only suitable material properties of the piezoelectric and elastic layers, but also their thicknesses, to improve the smart structure's fracture strength within a specified range.

This paper presents a nonlinear model for piezoelastic laminated plates with damage effect of the intra-layers and inter-laminar interfaces. Discontinuity of displacement and electric potential on the interfaces are depicted by three shape functions. By using the Hamilton variation principle, the three-dimensional nonlinear dynamic equations of piezoelastic laminated plates with damage effect are derived. Then, by using the Galerkin method, a mathematical solution is presented. In the numerical studies, effects of various factors on the natural frequencies and nonlinear amplitude-frequency response of the simply-supported peizoelastic laminated plates with interfacial imperfections are discussed. These factors include different damage models, thickness of the piezoelectric layer, side-to-thickness ratio, and length-to-width ratio.

This paper presents a nonlinear model for cross-ply piezoelastic laminated plates containing the damage effect of the intralayer materials and interlaminar interfaces. The model is based on the general sixdegrees-of-freedom plate theory, the discontinuity of displacement, and electric potential on the interfaces are depicted by three shape functions, which are formulated according to solutions about three equilibrium equations and conservation of charge. By using the Hamilton variation principle, the three-dimensional nonlinear dynamic equations of piezoelastic laminated plates with damage are presented. Then using the finite difference method and the Newmark scheme, an analytical solution is presented. In numerical examples, the effects of different damage models, damage evolution, amplitude and frequency of electric loads on the nonlinear dynamic response of piezoelectric laminated plate with interfacial imperfections are investigated.
