Fatigue strength of longitudinal load-carrying welds in beams made of ultra-high-strength steel
(Elsevier, 2021-02-06)
The present study experimentally investigates the fatigue strength of longitudinally loaded welded joints in beam structures made of ultra-high-strength steel. Hereby, the effects of different manufacturing methods and ...
Fatigue strength characterization of high and ultra-high-strength steel cut edges
(Elsevier, 2020-12-04)
This paper investigates the fatigue strength characteristics of CO2 laser, fiber laser and plasma cut edges of S690 and S1100 steel grades. The effect on fatigue performance of surface quality, which was examined by contact ...
Re-evaluation of weld root fatigue strength for load-carrying fillet welded joints using the notch stress concept
(Elsevier, 2020-12-09)
The re-evaluation of fatigue strength, applying nominal and notch stress concepts has been carried out, using extracted experimental fatigue data for load-carrying fillet welded joints failing from weld root. Various ...
Fatigue strength assessment of ground fillet-welded joints using 4R method
(Elsevier, 2020-08-29)
In the present paper, a fatigue analysis for welded joints made of mild, and high- and ultra-high-strength steel grades and post-weld-treated with grinding and combined grinding and peening methods is carried out using ...
Fatigue strength assessment of TIG-dressed ultra-high-strength steel fillet weld joints using the 4R method
(Elsevier, 2020-06-10)
Post-weld treatments can enhance the fatigue strength of weldments by means of improving their geometry or residual stresses, or both. In this study, the fatigue strength of TIG-dressed non-load-carrying cruciform joints ...
