Residual fatigue lifetime estimation of railway axles for various loading spectra
TL;DR: In this paper, the authors focused on numerical estimation of residual fatigue lifetime of railway axles while several different load spectra taken from the literature are considered in the performed estimations.

Fatigue resistance and remaining life assessment of induction-hardened S38C steel railway axles
TL;DR: In this paper, the residual stress field of induction-hardened S38C railway axles was reconstructed using a new unit pressure and proportional integral approach (UPA) instead of complicated heat simulation.

TL;DR: In this article, the authors present a methodology for the residual fatigue lifetime prediction of the railway axle based on the linear elastic fracture mechanics concept, which contains estimation of the critical position of initial crack, prediction of fatigue crack front shape development during crack propagation, separation of the bending and press-fitting contributions to the axle load, experimental measurement of the crack growth kinetics of EA4T steel and subsequent estimation of residual fatigue life of railway axle.

Seasonal variation effects on the formation of trihalomethane during chlorination of water from Yangtze River and associated cancer risk assessment
TL;DR: It was found that the presence of Fe(III) resulted in the increased level of THMs and greater cancer risk from exposure to humans and more attention should be given to the effect of the coexistence of Fe (III) and bromide ions on the risk assessment of human intake of TH Ms from drinking water.

The development of a damage tolerance concept for railway components and its demonstration for a railway axle
TL;DR: In this paper, a draft procedure for damage tolerance analysis of railway components is presented and illustrated by a case study on a railway axle, based on the recently developed European flaw assessment procedure SINTAP, the NASGRO/ESACRACK procedure for fatigue crack extension and other documents.
