In comparison to conventional engineering materials and composites, FGMs possess improved thermal and mechanical properties as well as higher corrosion and wear resistances.
For this reason, FGMs have wide range applications in engineering structures and components such as electronic devices, corrosion-resistant and wear-resistant coatings, optical films, thermal barrier coatings and bio-materials.
Fracture and damage behaviors of FGMs are especially important to their thermal and mechanical integrity, reliability and durability in engineering applications.
Crack analysis of FGMs may provide a deep insight into the failure mechanisms of FGMs, which may aid in the material design, optimization and processing of FGMs as well as their engineering applications.
