When two materials are bonded, free-edge stress singularity usually appears at the intersection of free surfaces and the interface. In recent years, anisotropic materials such as GFRP are used for making a bonded dissimilar materials. Present authors investigated the free-edge stress singularity of bonded dissimilar orthotropic materials theoretically by using the characteristic equation in terms of Airy's stress function. In this study, determination method of the presence of the free-edge stress singularity of bonded dissimilar orthotropic materials was proposed and the effectiveness of the method was evaluated numerically. Furthermore, the disappearance of the free-edge stress singularity by inserting an interlayer to the bonded dissimilar orthotropic materials, for which the free-edge stress singularity develops, was investigated theoretically and numerically.
