A Method for Calculating Nominal Structural Stress of Spot-Welded Structure - The spot welding near the flange edge

摘要

In order to improve the fatigue life prediction technology of the spot-welded structure by CAE, the calculating method to obtain the value of the nominal structural stress was proposed before in our laboratory. In this study, the improved technique which calculated the nominal structural stress value for the structure in which spot welding exists near the flange edge was proposed in order to attempt further practical application of the calculating method. It was shown that the excellent nominal structural stress for the spot welding near the flange edge could be obtained by proposed technique.
