摘要：

The focus of this paper is to study an infinite composite hollow cylinder consisting of a homogeneous piezoelectric layer and a functionally graded elastic layer. A general linear spring-layer model is employed to characterize the interface between the two layers, which may be perfect or imperfect. Directly based oil the three-dimensional exact equations of elasticity and piezoelasticity, the state space formulations are developed. An analytical characteristic equation is presented, from which the dispersion of wave propagating in the cylinder can be investigated. In numerical examples, different modes of wave propagation and the effects of some parameters on the dispersion curves are discussed.
