Summary
To gain an improved understanding of the synergistic effects of toughness and residual stresses, a simple beam-on-elastic foundation model of a longitudinally split rail was developed. This model supplemented finite element fracture mechanics analyses that were unable to effectively address these conditions. The findings of this research specifically indicate that, if the rail does not have adequate dynamic fracture resistance, rail residual stresses can give rise to crack driving forces that are sufficient to maintain a long-running web fracture. These results are quantitatively consistent with the absence of long-running dynamic crack propagation events in standard rail and with the actual occurrence of a fracture event in a premium alloy rail.
