Prediction of welding residual stresses and displacements by simplified models. Experimental validation

The assessment of residual stresses in welded high strength steel box sections

“…For plates II and IV, the widths of tensile residual stress zone (w-0.35 t) are approximately 13 mm-14 mm. The thermal envelope model presented in reference [21] is a good explanation for this phenomena.…”

Influence of thermo-mechanical material properties of different steel grades on welding residual stresses and angular distortion

“…Similarly, Goff et al [17] used temperature dependent yield stress while keeping remaining thermomechanical material properties constant for prediction of residual stresses with acceptable accuracy. Barroso et al [18] employed numerically different combinations of mechanical material properties and found that the longitudinal residual stresses in butt welded aluminum alloy plates can be predicted with reasonable accuracy if all the mechanical material properties are considered as constant in welding simulations. Canas et al [19] investigated the residual stress distribution in butt welded aluminum plates and observed that temperature dependent thermal properties as well as mechanical properties are irrelevant in the simulations.…”

Modeling, Prediction and Validation of Thermal Cycles, Residual Stresses and Distortion in Type 316 LN Stainless Steel Weld Joint made by TIG Welding Process

“…Asserin et al [9] made very detailed systematic sensitivity analysis to predict the important material properties for the simulation. Barroso et al [10] used simplified material model to reduce the solver time and performed semi destructive stress measurements for the prediction of residual stresses.…”
