Fatigue Strength Assessment of Welded Joints by Using Notch Stress Approach
نویسنده
چکیده
The fatigue strength assessment of welded joints by using the known parent material fatigue strength is considered in this paper. The stress concentration factor was determined performing FEA of singlesided transverse attachment joints for mean value of weld toe radius which was calculated by using several measurements of the weld toe radius along the weld length. The fatigue strength of welded joints was determined by taking into account the stress concentration factor, the hardness in HAZ, residual stress and misalignment. The results obtained by these calculations are compared with experimental results.

Ultrasonic impact treatment (UIT), which is a peening method, is usually used as a post-weld treatment in order to improve the fatigue strength of welded joints. In this study, fatigue tests were carried out on web-gusset welded joints treated by UIT and the results were compared with the fatigue lives of as-welded joints in order to examine the effects of UIT on the fatigue lives of welded joi...
متن کاملInvestigation of the Fatigue Strength of the Welded Joints Treated by Tig Dressing
The fatigue fracture of structural details subjected to cyclic loads mostly occurs at a critical cross section with stress concentration. The welded joint is particularly dangerous location because of sinergetic harmful effects of stress concentration, tensile residual stresses, deffects, microstructural heterogeneity. Because of these reasons many methods for improving the fatigue resistance o...
متن کاملThe Effect of Ultrasonic Peening Treatment on Fatigue Performance of Welded Joints
Ultrasonic peening treatment (UPT) as a method of severe plastic deformation was used to treat cruciform welded joints of Q345 steel. The application of UPT achieves material surface nanocrystallization of the peening zone, reduces stress concentration, and produces residual compressive stresses at the welded toe. Micro-structure, hardness, stress relief, S-N curve, and the fatigue fracture mec...
