STATE OF ART OF DYNAMIC ANALYSIS OF SANDWICHED FUNCTIONALLY GRADED MATERIAL

Abstract

In view of the numerous increases in research activity and publications in the Functionally graded material (FGM) and their structures within the previous couple of years, the present article is an attempt for the excellent review of the varied strategies utilized to check the dynamic behavior of the FGM plates. There are wide range of applications for Functionally Graded Material (FGM) and the applications are expected to extend as the cost of its fabrication and processing of the material are reduced by improving these processes. The attempt in this paper will be to present vibration, stress and buckling characteristics of FGM plates predicted by the help of many theories that are proposed by many researchers without considering the detailed mathematical implication of various methodologies used by them. There is a change in material properties through the thickness, type of load case, boundary conditions, the effect of nonlinearity, side-to-thickness ratio and edge on the behavior of FGM plates. Effort has been made, to include all the important contributions that are there in the current area of interest. The conclusion also includes the crucial areas that are used for future research needed the best implementation of sandwiched Functionally graded material are also given in the conclusions. The most important objective of this paper is to serve interests of the engineers and researchers that are already involved in the analysis and design of FGM structures.
