Event: JSAE Autumn Conference
In this study, the theoretical analysis method of shearing force through the spot welding, stresses and deformations around the spot welding on irregular pitch spot-welded box section beam which receives the torsion was proposed. In addition, bending-torsion finite element for the spot-welded member was proposed using local warping got from the proposed method. Stress analysis and torsional rigidity analysis of adjacency spot-welded member were carried out using these techniques. Stresses and torsional rigidity of adjacency spot-welded member were clarified, while the effectiveness of this technique was shown by comparing the results of experiment and finite element method.
