Abstract: Lateral track stability is a critical parameter in ballasted railway tracks considering track buckling. The sleeper type has a direct impact on lateral track stability. Due to the Y-shape sleeper tracks’ truss structure, ...

Abstract: In order to investigate the ultra-low cycle fatigue (UCLF) fracture in welded connections of high-strength steel (HSS) under earthquakes, this paper studies micromechanical fracture models for Q46C steel, which has wide ...
