Abstract:
Fatigue behaviour of welded aluminium joints with longitudinal and round stiffener subjected to bending loads are systematically investigated in this study. Fatigue analysis based on nominal stress range approach, two local approaches based on structural (hot spot) as well as notch stress respectively are applied. A possibility of using existing design S-N curves, usually assuming joints subjected to axial load, for the joints subjected to bending loads, was investigated in this work. Fatigue test results of specimens subjected to bending loads have been assessed using a nominal, structural, and notch stress range approach, and compared with appropriate design S-N curves.
