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. © 2019 Elsevier Ltd. All rights reserved.

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 * Corresponding author.
