Influence of Initial Inclined Surface Crack on Estimated Residual Fatigue Lifetime of Railway Axle
Original language description
Railway axles are subjected to cyclic loading which can lead to fatigue failure. For safenoperation of railway axles a damage tolerance approach taking into account a possiblendefect on railway axle surface is often required. The contribution deals with an estimationnof residual fatigue lifetime of railway axle with initial inclined surface crack. 3D numericalnmodel of inclined semi-elliptical surface crack in railway axle was developed and itsncurved propagation through the axle was simulated by finite element method. Presence ofnpress-fitted wheel in the vicinity of initial crack was taken into account. A typical loadingnspectrum of railway axle was considered and residual fatigue lifetime was estimated bynNASGRO approach. Material properties of typical axle steel EA4T were considered innnumerical calculations and lifetime estimation.
