Rationally-Based Structural Design of Welded Plate Panels

This study predicts the behavior of welded plate panels (unstiffened plates) with different geometrical properties (slenderness ratio and aspect ratio) in order to address a rational structural design procedure, as these parameters are great importance from perspective. Nonlinear finite element analysis has been used simulate butt-welding process panels, giving three-dimensional distribution distortion residual stresses induced by welding through moving heat source. The numerical results validated published experimental measurements. effect such slenderness β a/b on creation welding-induced imperfections (distortion stresses) have investigated this work. These influence imperfections, which turn affect load-carrying capacity panels. Three ratios three studied. It is concluded that increasing can highly increase out-of-plane magnitude well compressive stress. plates high (thin thicknesses) affected a/b. As increases, reduction ultimate strength due existence decreases. Slenderness smaller more than higher ratio.
