Numerical Estimation of Stresses in Railway Axles Using a Train-Track Interaction Model

The fatigue design of railway axles requires that the stresses arising in the axle in real service are accurately quantified. This paper describes a method to compute the dynamic stresses arising in railway axles as the effect of train track interaction, based on the numerical simulation of the dyna...
