article description
This study deals with the stress intensity factors (SIFs) in two dissimilar functional non-homogeneous materials containing cracks perpendicular to the interface. Assuming that the shear moduli of the materials vary exponentially with the spatial coordinates, the problem is reduced to the solution of a singular integral equation with a generalized Cauchy kernel. It is shown that the stresses possess the usual square-root singularity when the crack is fully embedded in one medium, but the singularity is dependent on m when an end of the crack is located at the interface. The singular index β decreases with increasing m, but is independent of αK.
