  4. 2. Rolling Contact Fatigue of Railway Wheels Towards Tread Life Prediction through Numerical Modelling Considering Material Imperfections, Probabilistic Loading and Operational Data

    Author : Anders Ekberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Higher train speeds and increased axle loads have led to larger forces acting on the railway wheels. Also, efforts are presently being made to straighten existing tracks, to design new tracks with larger curve radii and to optimize bogie designs. READ MORE

  7. 5. Probabilistic high cycle fatigue models - volumetric approaches

    Author : Salar Sadek; Mårten Olsson; Anders Ekberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Fatigue is the most frequent failure mode and must be considered in a mechanical designof actual operating components. The fact that mechanical design is most often linkedwith existence of stress raisers and multiaxial time-varying stresses has in the last decadesincreased the research effort worldwide. READ MORE
