Abstract:

This paper researches the influence of elastic modulus of adhesive on the single lap joint of aluminium alloy, using elastic-plastic finite element method (FEM). Through analyzing the stress distribution of adhesive layer and the stress distribution of adherend, showing that the influence of recessed bonding on the stress distribution of joint in the end is not evident, but the influence of recessed bonding on the peak stress near the recessing is greatly. The higher the elastic modulus of adhesive, the smaller the peak stress near the recessing.
