Analysis of Spot-Welded Stiffened Plates under Compression Loading for Automotive Applications

Abstract This research focuses on improving the structural performance and safety of automotive components through the optimization of spot-welded stiffened structures. Experimental investigations were conducted alongside Finite Element Analysis (FEA) to evaluate the strength and deformation behaviour of spot-welded assemblies under various loading conditions. The findings of this study offer valuable insights into enhancing the crashworthiness and reliability of automotive structures, thereby contributing to vehicular safety.
