The fatigue crack propagation threshold Δ K th is of paramount importance for any kind of
damage tolerant design, but in contrast to this importance, the determination and application …

The paper gives an overview on safe life and damage tolerance methods applied to railway
axles. It describes failure scenarios due to fatigue crack initiation and propagation. Besides …

The remaining life assessment of damaged railway axles is an important topic primarily
because of extending the maintenance interval. However, the fatigue resistance of surface …

Fatigue crack-growth of mechanical components is stochastic in nature and deterministic
approaches do not allow for its complete study. Primary sources of this stochasticity can be …

Railway axles are safety relevant components which are usually designed for up to 30years
of service. Besides the experience based definition of inspection intervals, the application of …

The reliability of the damage tolerance approach to engineering design is affected by
numerous sources of uncertainty that can lead to unsafe predictions, in turn jeopardizing the …

The fatigue properties of railway axle steels have not yet been thoroughly studied even
though a number of axle failures are undoubtedly due to the combined effects of corrosion …

The present paper summarizes the results of fatigue crack growth investigations on a hollow
railway axle which were undertaken as a joint research project between the Politecnico di …

From the viewpoint of engineering applications, the prediction of the failure of railway axles
plays an important role in preventing the occurrence of fatigue fractures. Combining a …

Railway axles are designed to be highly reliable so as to ensure even more than 30 years of
service. Even though they are periodically inspected by scheduled Non Destructive Testing …
