Evaluation of stress intensity factor in FGM
Original language description
Functionally graded materials (FGM) are characterised by variations in their material properties in terms of their geometry. They are often used as a coating for interfacial zones to protect the basic material against thermally or mechanically induced stresses. FGM can be also produced by technological process for example butt-welding of the polymer pipes. This work is focused on a numerical estimation of the stress intensity factor for cracks propa-gating through FGM structure. The philosophy of the FEmodel creation is focused on the discretization of mate-rial 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. Thethickness effect of the FGM layer is also discussed. All analyses are simulated as a 2D problem of an edge crack specimen. In this pa-per, the above effects are quantified, and conclusions concerning the applicability of the proposed mod
