Elasticity Solutions for Cylindrical Bending of Functionally Graded Piezoelectric Material Plates

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 has broad application prospects in electronic devices. Based on the elastic and electric equilibrium equations, the Mian and Spencer functionally graded plate theory was extended from elastic materials to piezoelectric materials to study the cylindrical bending of FGPM plates, where the material elastic constants, piezoelectric and dielectric parameters were assumed to vary continuously and arbitrarily along the thickness direction. Accordingly, the elasticity solutions for cylindrical bending of FGPMs plates under the uniform transverse loading were obtained. Numerical examples were given to demonstrate the piezoelectric effects on the static responses of the presented FGPMs plates.
