Abstract

In order to overcome the interfacial stress concentrations of the traditional layered piezoelectric elements, functionally graded piezoelectric materials with material properties changing smoothly and continuously along certain direction have been developed. At present it has becoming a new research hotspot. Based on the three-dimensional elastic theory of piezoelectric materials and assuming that the mechanical and electric properties vary continuously along the thickness direction and have the same exponential distribution, the static analysis of functionally graded piezoelectric annular sectorial plates with simply supported radial edges and arbitrary circular edges is achieved in this paper using a semi-analytical method which makes use of the state space method along the graded direction and the one-dimensional differential quadrature method along the radial direction. The accuracy, convergence and superiority of the present method are demonstrated through numerical results. The effect of material graded index on the electromechanical coupling behavior of functionally graded piezoelectric annular sectorial plates is studied. The results obtained from the numerical example may be useful for the design of functionally graded piezoelectric annular sectorial plates.
