Fatigue strength assessment of ultra-high-strength steel fillet weld joints using 4R method
(Elsevier, 2019-11-30)
A fatigue analysis on experimentally tested transverse fillet-welded non-load-carrying T- and X-joints made of S960 and S1100 ultra-high-strength steel was carried out in the present study. The test data consisted of welded ...
Use of the quasi-static Johnson-Cook model in the failure assessment of tensile specimens with metallurgical constraints
(Elsevier, 2020-04-10)
Direct quenching has recently been used to develop cost-effective novel high and ultra-high strength steels. In weldments made of these steels, a distinct soft zone, which can lower the ultimate strength and deformation ...
Mechanical properties and microstructural evaluation of the heat-affected zone in ultra-high strength steels
(Elsevier, 2020-09-17)
This paper presents an investigation into the mechanical properties of ultra-high strength steels (UHSSs) (with nominal yield stress of 960 and 1100 MPa) after welding. Seven weld thermal cycles were simulated using a ...
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 ...
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 ...
