Abstract

We present the intensity of stress singularity for 3D dissimilar material joints based on mesh free method. When load is applied to surface of the bonded structure, stress at vertex on interface drastically increases and it appears that this stress singularity occur delamination of the bonded structure. Intensity of stress singularity can be expressed by stress distribution and the intensity of stress singularity. Therefore, it is necessary to obtain the stress distribution precisely. In this study, we focus on the mesh free method for the computation of the stress distribution. When this method is applied to compute stress distribution, incompatible cell can be employed and geometrical data for a target structure can be simply prepared. To confirm the validity of the results of mesh free method, comparison of the intensity of stress singularity between the mesh free and the boundary element methods is carried out.
