DOI: 10.1007/s12289-020-01590-9
Abstract: Railway axles, which are an important component of railway vehicles, are generally manufactured using high-speed forging processes. To investigate the microstructure evolution and flow behavior during forging processes, a series of isothermal hot compression and… read more here.

DOI: 10.1016/j.engfailanal.2016.12.014
Abstract: Abstract The railway axles are subjected to cyclic loading during their operation. Their load is of long-term nature, therefore a real risk of fatigue failure exists. This failure could lead to derailment of the whole… read more here.

DOI: 10.1016/j.engfracmech.2018.04.046
Abstract: Abstract Railway axles with inside axle boxes have a great potential in modern urban railway system due to good dynamic performance on small-radius track. However, because of entirely different loading nature from widely-used one, a… read more here.

DOI: 10.1016/j.ijfatigue.2016.12.025
Abstract: Abstract The design guides of railway axles prescribe these axles to have an infinite life based on fatigue limit and to estimate the local stresses in transition fillets or grooves by using the nominal stresses… read more here.

DOI: 10.1016/j.ijfatigue.2019.105371
Abstract: Abstract To investigate the effect of plastic deformation and fretting wear on the fretting fatigue of scaled railway axles, three fatigue assessment methodologies are developed, namely elastic-fatigue, elastoplastic-fatigue and wear-fatigue methodologies. Elastic material behaviour, elasto-plastic… read more here.

DOI: 10.1016/j.ijfatigue.2020.105753
Abstract: Abstract The in-service safety of railway axles is a very important engineering challenge, as it has a large impact not only from the economic point of view of the railway operator, but it has cascading… read more here.
