Numerical Analysis of Residual Stresses in a T-Joint Fillet Weld Using a Submodeling Technique

A submodeling technique is applied in the framework of this study on a Tjoint fillet weld example in order to check finite element mesh sensitivity as well as to obtain more accurate temperatures, displacements and residual stress fields in the weld and its vicinity where the temperature and stress gradients are very high. The submodeling procedure of the welding process is demonstrated step-by-step. The obtained results of the temperature, residual stress and displacement distributions correspond very well with the experimental measurements and analytical solutions from the literature.
