Residual stress effects on fatigue crack propagation in Butt–Welded joints for 304 stainless steel sheets

Abstract: Welded joints are sensitive to fatigue failure due to cyclic loading, as well as fatigue crack propagation influenced by the distribution of welding residual stress. In this study, the fatigue crack propagation rates in butt-welded joints for 304 stainless steel sheets were evaluated in the presence of welding residual stresses. The analysis consisted of two separate models: first, a 3D-finite element (FE) model was used to predict the residual stresses due to welding; second, a numerical study was undertaken … Show more

“…The analysis is conducted through four distinct simulations, each corresponding to an individual pass of the PTCAP process. To accurately represent material work hardening, the pertinent result variables are also transferred accordingly, as outlined in the study [30]. To accurately implement contact constraints, which govern the interaction between surfaces (surface-tosurface contact) definition is essential.…”
