A finite Element Approach to Nonlinear Free Vibration of a Spherical Shell Panel Utilising Higher Order Shear Deformation Theory
Received Date: Jan 20, 2022 / Published Date: Feb 28, 2022
Abstract
Examine the nonlinear free vibration response of a spherical shell made of functionally graded materials (FGMs).
Temperature independent (TID) material qualities are used to subject it to uniform and non-uniform temperature changes.
The basic formulation is based on higher order shear deformation theory (HSDT) with Von-Karman nonlinear strains using modified C0 continuity. A direct iterative based nonlinear finite element method combined with mean centered first-order perturbation technique (FOPT) proposed for the Functionally Graded Materials plate is extended for spherical shell subjected to thermo-mechanical loading. The present outlined approach will be validated with those available in literature.
