Abstract
The influence of process parameters on the residual asymptotic stress distribution is investigated using a 3D numerical modeling of the welding process. Computational welding mechanics and the peak stress method are combined to calculate the residual Notch Stress Intensity Factors (R-NSIF) as a function of power input. Results are summarized in terms of heat input and discussed in view of a future guidelines proposal addressed to designers who are going to face a welding process optimization for fatigue life improvement. © 2022 Elsevier Ltd| File | Dimensione | Formato | |
