Abstract: 

Functionally graded materials (FGMs) are composites that their properties change as a continuous function of position. For the first time in 1984, the Japan aerospace laboratory employed the materials which were produced with heterogeneous microstructure and their mechanical properties gradually and continuously varied from one surface to another. Due to the continuity in change, residual stresses and the stress intensity factors (SIFs) are reduced. FGMs include wide range of commercial applications such as tools, biomedical devices, optical fibers and coatings resistant to abrasion and heat.
Researches reveal that the most common failure mode in these materials is crack initiation and its growth. …
