Adhesive bonding is a method used to achieve a connection and immobilization.The metal sheets connected by adhesive joints have a wide range of applications in the automotive industry,construction and aerospace.We use the finite element method to study the slipping and failure behavior of metal sheets with adhesive joints under tensile load,focusing on the adhesive energy of the adhesive layer,overlap length and glue layer thickness on the adhesive capability of the joints.The results show that increasing the adhesive energy can significantly improve the load bearing capability of adhesive joints.And the overlap length and the adhesive energy have combined influences on the load-bearing capability.Raising the overlap length can significantly improve the load bearing capability for the cases of larger adhesive energy.The load bearing capability can also be influenced by the thickness of adhesive layer,which is that increasing the thickness can enhance the load bearing capability in the thickness range considered in this paper.Finally,the damage of adhesive layer is considered preliminarily when the load increased to the peak value.
