Abstract
    The automotive industry extensively uses advanced high-strength steels for structural applications, raising challenges related to the mechanical performance of resistance spot-welded joints. This study numerically investigates the tensile–shear behavior of spot-welded steel plates made of TRIP800, DP450, and DP980 using a three-dimensional finite element approach. The objective is to evaluate the influence of material type and applied load on stress distribution, mechanical response, and safety factors. The results show significant stress concentration near the weld nugget, with a symmetrical distribution in the transverse direction and an asymmetrical pattern along the loading direction. DP450 and TRIP800 exhibit earlier loss of elastic behavior compared to DP980, although all materials maintain adequate safety margins at maximum load levels. These findings underscore the significance of material selection in ensuring the structural integrity of spot-welded automotive components.
