Abstract
A semi-analytical model is proposed for the stress and displacement analysis of all-round simply supported functionally graded (FG) piezoelectric laminated plates in this paper. Material electric and elastic properties have been assumed to vary according to the exponential law as well as power law in the thickness direction, considering the Poisson’s ratio to be an invariant. Formulation part is based upon the theory of elasticity and numerical integration technique has been employed to obtain the solutions. Mathematical model developed is a set of mixed first ordered ordinary differential equations (ODEs), which has been validated by comparing the results obtained with exact solutions available in literature. Several examples have been addressed to ascertain the versatility of the model. Additional investigation has been carried out on FG piezoelectric plates and results provided for future reference.
