A state of the art in Functionally Graded Materials and their Analysis

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. (C) 2019 Elsevier Ltd. All rights reserved.
