Effect of Thickness in Intermediate Layer on Intensity of Stress Singularity at a Vertex in Three-Dimensional Bonded Joints
In the present paper, singular stress fields at the vertex on the interface in three-dimensional bonded joints are analyzed using BEM. The order of stress singularity is determined solving an eigen equation based on FEM formulation and the stress distribution is expressed using the result of the eigen-value analysis. A simple relationship between the thickness of layer and a value of stress is introduced. Then, stress distributions for various thicknesses of layer are unified using the relationship, and the unified intensity of stress singularity is determined.
