AImtractmsmall crack d~ection in brittle functionally graded materials (FGMs) is studied. The FGMs are modeled as simply nonhomogeneous materials, i,e., the effect of microstructurΒ’ is neglected and the material property variation is considered to be continuous. Considering local homogeneity and the

The homogenisation theory for periodic composites is generalised to the case of quasi-periodic composites. In quasi-periodic composites, the unit cell does not repeat throughout the medium but gradually changes along one or more directions of periodicity (grading directions). Quasi-periodic composit
The present communication is concerned with a numerical procedure to determine an optimal material layout of a functionally graded material (FGM) within the context of a transient phenomenon. In particular, the physical problem considered here is transient heat conduction. The idea is to determine t
## Abstract A numerical method is proposed for analysing transient waves in plates of functionally graded material (FGM) excited by impact loads. The material properties of the FGM plate have a gradient in the thickness direction and are anisotropic in the plane of the plate. In the present method,
One of the main interests of fracture mechanics in functionally graded materials is the influence of such an inhomogeneity on crack propagation processes. Using the Griffith' energy principle, the change of energy has to be calculated, if the crack starts to propagate. In homogeneous linear-elastic
