Abstract

The finite element method was used to study the Influencing Factors on Stress Distribution of Weldbonding Joint under Bending Load. The results show that after welding-reinforced with welding spots, the initial point of compromise is shifted from the end of the glue layer to the connection of the glue layer with the welding spots, which means the overall capacity of the joint has been enhanced, since the yield strength of the welding spots is far greater than that of the glue layer. This suggests that the compatible deformation of the welding spot and the glues under bending load will be improved with higher elastic modulus of the glues. As the thickness of the glue increases, the crushing stress on the left part decreases gradually along with the tensile stress on the right, which also helps to shape the stress distribution in the joint more evenly.
