Abstract :
Based on the simplified theory, free vibration in three-dimensional functionally graded piezoelectric plates is analyzed. The first-order shear deformation theory and state space method are utilized in directions z and x, respectively. The plate is simply-supported in direction y, so a generalized Levy solution is obtained. Numerical examples show that the vibration behavior depends considerably on different boundary conditions and material properties. The results can provide a theoretical basis for the dynamic characteristics of three-dimensional plate with complex boundary conditions.
