English Title : Investigation of the e ects of the weld groove shape on the residual stress formation in the butt-welded plates
English Abstract : In this investigation, nite element technique and experimental method were utilized for analyzing the residual stresses created during the welding process of plates. In this way, a welded specimen was prepared with controlled welding parameters. Hole drilling technique was used to measure the residual stresses in some points of the welded specimen. To evaluate accuracy of the FE modeling, a comparison between experimental data and FE results was utilized and showed a good agreement. According to this study, the procedure of the FE modeling with acceptable accuracy was extended. This improved model was employed to investigate the in fluence of the groove shape on the remained stresses of welded plates. It was shown that the weld groove shape can a ect the distribution of the remained stresses in thick welded plates, but it had no signi cant e ect on peak stresses.
English Keywords : Remained stresses; Finite element technique; Butt-welded plate; Groove shape.
