Introduction Due to the inherent coupling nature, piezoelectric materials and piezoelectric/piezomagnic materials have attracted wide application in engineering.
Piezoelectric materials and piezo- electric/piezomagnic materials in mechanical behavior are brittle and susceptible to crack- ing, Therefore, it is important to study the electro-magneto-mechanical interaction and fraction behavior of those materials.Great efforts have been made to study the fracture behavior of the materials.

Functionally graded materials. finite element method Abstract.
Introduction Functionally graded materials (FGMs), as a kind of typical nonhomogeneous materials, have excellent thermomechanical properties and have absorbed great attention from many scholars in recent years.
The results indicate that the TSIF at the early stages of thermal shocks are dominant factors for fracture failure of the materials.
