Electro-mechanical vibration characteristics of functionally graded piezoelectric plates with general boundary conditions

This paper describes a unified approach for free vibration and transient response of functionally graded piezoelectric plates with different boundary conditions on the basis of first order shear deformation theory. Both effective electrical and mechanical properties of the plate are estimated by the Voigt model combined with a simple power-law distribution. The formulation is derived by variational principle in conjunction with penalty function...
