ABSTRACT
Use elastoplastic finite element method to analyze the combination effect influence of weldbonding joint. It can be seen from paper that as to the weldbonding joints under peeling and bending load; the reinforcement of the glue-welding combination is relied on the adhesiveness between the glue and the welding point. Disconnect the glue layer from the welding point to disintegrate the glue-welding combination, leaving the glue layer barely loaded and the stress concentration in the welding point becomes very significant and the stress peak of the joint increases drastically, with the bearing capacity and rigidity of the reinforced joint drops considerably. Therefore, adhesion quality is key to the Weldbonding joint under peeling load and must be guaranteed. Therefore, the composition of the existing epoxy glue shall be modified; also shall new approaches be probed in order to enhance the elastic modulus of the epoxy glue, e.g., to develop new additives to improve the performance of the glue, in order to excavate its potential high strength.
