If two dissimilar materials are joined at high temperature, very high residual stresses develop near the free edge of the interface during cooling to room temperature. In most cases, the stresses are singular for elastic material behaviour. One method to avoid the stress singularities is to introduce a graded interfacial zone with a continuous change of all material properties between the two joined components. In this paper the distribution of the stresses in FGM has been calculated by FEM. The interlayer has continuous material properties, which means that the graded interlayer has not been treated as N layers. The value of the peak stress and the location of the peak stress in the joint have been investigated.
