The free-edge stress singularity usually develops near the edge of the interface of the bonded dissimilar materials. Anisotropic materials may be used for making bonded dissimilar materials. When two materials are bonded, an interlayer, for example an adhesive layer, may be inserted between two materials. In this study, free-edge stress singularity of bonded dissimilar orthotropic materials with an interlayer was investigated by using the boundary element method. It was found that the influence of the interlayer on the stress distribution on interface was limited in the region of the order of the interlayer thickness around the edge of interface similar to the bonded dissimilar isotropic materials. Free-edge stress singularity disappeared by inserting a proper materials between the bonded dissimilar materials.
