Abstract

In this article, the hygrothermal postbuckling behaviour of multiscale doubly curved piezoelectric shells (MDCPS) has been evaluated through multiple scales perturbation method. The multiscale composite constituting of polymer/carbon nanotube/fiber and polymer/graphene platelet/fiber (PGF) in accordance with Halpin�Tsai model is considered for evaluation. The kinematics of the MDCPS is assumed to follow third order shear deformation theory (TSDT) and the non-linearity in the strain�displacement relation is adjudged through Von Karman relationship. Further, with the aid of Hamilton�s principle the governing equations of motion are derived. The present work studies the load�deflection curves for various distribution patterns such as U (uniform), X, A and O. In addition, the influence of various prominent parameters like applied voltage, magnetic potential, aspect and curvature ratio on the postbuckling characteristics of MDCPS is studied thoroughly.
