Abstract
Functionally graded piezoelectric materials (FGPMs), combining the properties of functionally graded materials and piezoelectric materials, provides a new idea for multi-functional and intelligent lightweight components, and it has broad application prospects in electronic devices. Based on the elasticity and electric equilibrium equations, the Mian and Spencer functionally graded plate theory is extended from elastic materials to piezoelectric materials to study the cylindrical bending of FGPM plates, where the material elastic constants, piezoelectric and dielectric parameters are assumed to vary continuously and arbitrarily along thickness direction. Accordingly, the elasticity solutions for cylindrical bending of FGPMs plates under the uniform transverse loading are obtained. Numerical examples are given to demonstrate the influence of piezoelectric effects on the static responses of the presented FGPMs plates.
