Abstract

In the present study, a functionally graded cylindrical shell (FGM) with imperfectly surface bounded functionally graded piezoelectric material (FGPM) subjected to an axisymmetric hygrothermo-electro-mechanical loading and placed in a constant magnetic field is considered. The shell is simply supported and could be rested on an elastic foundation. The material properties of FGM and FGPM are assumed to be exponentially graded in the radial direction. The Fourier series expansion method through the longitudinal direction and the differential quadrature method across the thickness direction are used for solving governing differential equations. To check the validity of the present work, comparisons with the previous results are performed. Finally, numerical results are shown to clarify the effects of important parameters on the behavior of the smart shell. The multiphysics analysis is carried out to explore the effect of moisture, temperature, electric, and mechanical loadings as well as magnetic field on the behavior of the hybrid shell.
