In this paper, the problem of bonded dissimilar, homogeneous media with a functionally graded inter layer weakened by two parallel, edge interfacial cracks is investigated under the state of antiplane deformation. The Fourier integral transform method is employed to reduce the crack problem to a system of singular integral equations with generalized Cauchy kernels, which is solved based on the expansion collocation technique. In the numerical results, parametric studies are conducted such that the mode III stress intensity factors are evaluated, addressing the interaction between the two neighboring edge cracks strongly affected by geometric and material parameters of the bonded system.
