Abstract
Functionally Graded Materials (FGMs)are the new advance quality materials in the field of composites with respect to their
strength, mechanical and thermal properties. Now days, the modern requirement of industry in the field of aerospace and power
sectors needs the rapid evolution of new components, which provides the researchers to invent new materials in order to satisfy
the functional requirements of modern technology. Due to excellent heat resisting property along with resistance to corrosion,
erosion and fracture of FGM materials, these are used as smart materials in modern technologies. With the excellent thermal
properties of FGM, these are also having erosion and corrosion resistant and high fracture resistant. In this paper, the different
fundamental analysis like free, forced, buckling and thermal effect of FG beam along with the governing differential equations of
motion have been presented. The power law variation and corresponding material properties change in axial and transverse
direction of FG beam is also discussed.

1. Introduction
A functionally graded material (FGM) is made of different materials whose properties gradually varies from one
layer to another layer either in axial or in thickness direction. The FGM structures are being widely applicable in
high temperature areas like turbine blades, combustion chambers, automobile, nuclear power plant, aircrafts, space
vehicles etc. As these structural members are subjected to the vibrations, therefore there is a necessity to analyz the
vibrational properties like natural frequency of free vibration, forced vibration and buckling and thermal analysis of
FGM structures mainly used as beams. As in the case of laminated composites, there shows a mismatch in
properties at the interface of material and also having a large concentration of stress and there is a possibility of
