Abstract
The free-edge stress singularity usually prevails at the edge of the interface of the bonded dissimilar materials. Anisotropic materials are often used to make a bonded dissimilar materials. When two materials are bonded, an interlayer 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 free-edge stress singularity disappeared by inserting a proper material between the bonded dissimilar materials which has a free-edge stress singularity at the edge of interface.
