Abstract: In the present work, study of geometric nonlinear vibration analysis of thin piezolaminated functionally graded cylindrical shell is presented. Material properties are graded in the thickness direction of the shell according to power law distribution in terms of volume fraction of the constituents. The shell is modelled using degenerated shell element to predict the deformation under electric voltage and thermal gradient across the thickness of the shell. Modelling is based on the first order shear deformation theory. Second-Piola stress and Green-Lagrange strain tensor are used to perform the large deformation analysis. The accuracy of the developed finite element modelling is validated by comparing numerical results with the published results in the literature. The influence of electric voltage, thermal gradient and gradient index on the vibrational behaviour of cylindrical shell is studied.
