Assessment of weld root fatigue strength of load-carrying fillet welded joints using notch stress approaches and finite element analysis
(Lappeenranta-Lahti University of Technology LUT, 2023-11-21)
This thesis uses nominal and notch stress concepts to evaluate the fatigue strength of loadcarrying fillet welded joints (LCFWJs) made of high-strength steel. The study investigates the effect of different reference radii ...
