Abstract

The purpose of the paper is to develop an analytical investigation on free vibration of a simply supported functionally graded(FG) doubly curved shell panels resting on elastic foundation in THERMAL ENVIRONMENT. Heat conduction and temperaturedependentmaterial properties are both taken into account. The temperature field considered is assumed to be a uniformdistribution over the shell surface and varied in the thickness direction only. Material properties are assumed to be temperaturedependent and graded in the thickness direction according to a simple power law distribution in terms of the volumefractions of the constituents. Based on the first-order shear deformation theory and applying the Hamilton’ s principle, governingequations of motion are derived. The results of the study are compared with the available published literature. Thenumerical results obtained reveal that the material volume fraction index, geometrical parameters and temperature changehave significant effects on natural frequencies of the FG doubly curved shell panels.
