Abstract
This thesis employs a numerical method to analyze vibration of piezoelectric thin to moderately thick Rectangular and circular laminated plates on the basis of the first-order shear deformation theory (FSDT) and Rayleigh-Ritz method. The plate is modelled using single layer plate theory in mechanical aspect and layer-wise approach in the electrical part in order to represent the nonlinear behaviour of the electric potential along the thickness. The finite element method based on P-Type solution has been applied to implement the proposed model. Tn the present study, the dynamic response of the annular piezoelectric sandwich plates is extensively investigated. Also new results are provided for vibration of circular bimorphs for different thickness-radius ratios, inner-outer radius ratios, thickness of piezoelectric, and boundary conditions. It is observed that proposed model has performed very efficiently and provides optimum solutions and accurate results for thin to moderately thick piezoelectric plates.
