Influence of welding sequence on welding deformation and residual stress of a stiffened plate structure
TL;DR: In this article, the authors deal with welding simulation of a stiffened plate structure with longitudinal and transverse stiffeners using a thermal elasto-plastic FE method, where shell elements with section integration features are adopted to model the plate and stiffeners and solid elements to model local detail of weld line region.

TL;DR: In this article, a numerical model is developed for the welding and subsequent loading of a fabricated structure, which treats the weld process as a thermo-mechanical problem, and the model includes finite strain effects during isothermal loading, so that it may be used in the modeling of distortion sensitive structure.

Welding deformation and residual stress prevention
TL;DR: Welding Deformation and residual stress prevention is addressed in this paper, where the authors provide a unique computational approach to the prediction of the effects of deformation on materials and the goal is to provide engineers and designers with the ability to create their own computational system for predicting and possibly avoiding the problem altogether.
