Parametric Studies on Vibration Response of FG Shell Panels

Functionally graded (FG) material is an advanced composite material which is comprised of metal and ceramic, since metal is good in strength and ceramic is good in heat resistance. FG materials find their wide applications in different industries, viz., in aircraft, spacecraft and automobile structures, civil engineering, military industries, and marine structures. The material properties of a (FG) panel usually varies in one direction depending on some particular function. In the present research work, parametric studies have been conducted on different FG shell panels. The material properties are varied along thickness of the panel and are determined using the power law. Forced vibration response analysis has been conducted on FG panels having different shapes, such as conoidal, cylindrical, and spherical with R/W ratio of 5, 10, and 50. Four types of boundary conditions, viz., all edges clamped (CCCC), all edges simply-supported (SSSS), two opposite edges clamped and rest are simply-supported (CSCS) and three sides simply-supported and one edge free (SFSS) have been considered for the numerical simulations. The shell panel is modeled using an in-house ANSYS Parametric Design Language Code and finally the averaged quadratic velocity of the panels is computed in the MATLAB platform by importing the displacement data from ANSYS by varying different parameters.
