TL;DR: The shrinkage volume method as discussed by the authors is a linear elastic finite-element modeling technique that has been developed to predict post-weld distortion and residual stress in a carbon steel plate with different vee-butt preparations.

TL;DR: In this article, a split heat source model was developed to model the arc heat and the accuracy of the predicted cooling times, weld penetrations and lengths of the weld pools were compared with experimentally obtained values for bead-on-plate welds.

TL;DR: In this paper, a mathematical model is developed to predict the overall effect of the influencing weld geometry parameters such as (e.g. weld toe radius, weld toe undercut, flank angle, plate thickness, misalignment) and residual stresses on the fatigue strength and fatigue life of butt-welded joints subjected to combined loading (tensile and bending).

TL;DR: In this paper, the effect of residual stresses and weld geometry on the fatigue life of butt welded joints was studied by developing an analytical model using Linear Elastic Fracture Mechanics (LEFM), superposition and finite element approaches.

TL;DR: In this article, the effect of important Butt weld geometry parameters e.g. tip radius of undercut at weld toe, weld toe radius, flank angle, plate thickness and edge preparation angle on the fatigue crack propagation life have been studied by using Linear Elastic Fracture Mechanics (LEFM), Finite Element Analysis (FEA) and superposition approaches.
