Abstract: The concept of functionally graded (FG) materials was first introduced in 1984 by a group of material scientists in Japan, as ultrahigh temperature resistant materials for aircraft, space vehicles and other engineering applications. FG materials are a class of composites that have a continuous variation of material properties from one surface to another and thus eliminate interface problems found in laminated composites. The gradation in properties of the material reduces thermal stresses, residual stresses and stress concentration factors. The gradual variation results in a very efficient material tailored to suit the needs of the structure and, therefore, designated as a FG material. FG materials are typically manufactured from isotropic components such as metals and ceramics since they are used as thermal barrier structures in environments with severe thermal gradients. FG materials have the advantage of heat and corrosion resistance typical of ceramics and mechanical strength and t...
