Numerical results show the effects of the material gradient parameter and crack configuration on the field intensity factors of the crack.
Introduction In recent years, functionally graded materials~(FGM) have been widely introduced and applied to the development of thermal and structural components due to its ability not only to reduce the residual and thermal stress, but also to increase the bonding strength and toughness as well.
Particularly in the fracture of non-homogeneous materials initiating from the flows in the close neighborhood of phase boundaries, such as in the growth of microflaws in polycrystals and cracks in composites, the third mode of fracture is quite important.
