To evaluate the effectiveness of VFT for predicting distortion in thin structures, a bead-on-plate specimen, a butt joint of two large plates, and a long T stiffener were analyzed with VFT welding modeling software. It is more complicated to simulate the welding of thin structures than thick structures because buckling distortion often occurs during the welding of thin structures. and European shipyards have shown strong interests in using the software to predict and control welding distortion of thin-plate ship panels. Virtual fabrication technology (VFT) weld modeling software has been mainly used in thick-structure welding simulation.
