Description	This work is focused on a numerical estimation of the stress intensity factor for cracks propa-gating through FGM structure. The philosophy of the FE model creation is focused on the discretization of material properties. The analysis of the FGM layer bonded from both sides with different homogenous materials has been performed to study the influence of the shape of the material property change. The thickness effect of the FGM layer is also discussed. All analyses are simulated as a 2D problem of an edge crack specimen. In this paper, the above effects are quantified, and conclusions concerning the applicability of the proposed model are discussed.
