G010013 Singular stress field analysis for adhesive joints under the tensile shear load

Abstract

A mismatch of different material properties in joints may cause stress singularities at the edge of interface, which lead to the failure of the bonding part in structures. Therefore, it is important for the bonding strength of the joints to estimate three-dimensional stress singularity at the vertex. In this paper, a boundary element method is used for evaluating the intensity of stress singularity. A model for analysis is three-layered joints. The singular stress field is investigated by changing the material property of adhesion layer.
