What is Welding-Induced Stress in Stiffened Panels about?

This article discusses how welding-induced residual stresses and distortions can reduce the strength of flat-bar stiffened steel panels. Finite element modeling is used to simulate residual stresses and distortions from welding and analyze the behavior of stiffened panels under compression. Results show welding residuals can reduce panel strength by up to 18%. Load-shortening curves from modeling agree with design formulas for strength, but some discrepancies exist for post-ultimate behavior. Accounting for
