These volumes contain contributions from a conference on the themes of measurement and prediction of residual stress in railroad rails. Volume I contains elements of practical railway experience, laboratory tests, including experimental stress analysis, and theoretical evaluations of residual stress, crack propagation, and rail fracture. Theoretical and numerical analyses are presented in Volume II, in the hope that models based on solid mechanics can correlate the experimental stress measurements and lead to better understanding of the effects of residual stress upon crack propagation, fracture, and ultimately the economics of rail in the modern railroad environment.

This volume presents a collection of papers on the theme of rail integrity, which were presented at a meeting in Delft from 24th-26th June, 1992. Rolling contact fatigue is a failure mode which is increasingly being recognized as a threat to the reliability of modern heavy freight and high speed railway systems. These papers describe the current understanding of the problem and what rail steel technology and maintenance procedures have to offer to combat it.

Rail integrity is a current application of engineering fracture mechanics at a practical level. Although railroad rails have been manufactured and used for more than a century, it is only in the last ten years that the effects of their crack propagation and fracture characteristics have been considered from a rational viewpoint. The J,Jractical objectives are to develop damage tolerance ~delines for rail inspection and to improve the fracture resistance of new rail productiOn. Rail fatigue crack propagation rates and fracture resistance are strongly influenced by residual stresses, which are introduced into the rail both during proouction and in service. Therefore, the rail residual stress field must be well understood before fracture mechanics can be usefully applied to the subject of rail integrity. The three-dintensional character of rail and its stress fields make it essential to apply both experimental and analytical methods in order to twderstand the effects of pro duction and service variables on residual stress and the effects of the stress on fatigue crack propagation and fracture. This volume brings to~ether field observations and experimental stress analysis of railroad rails in the Umted States and Europe. The ongoing search for an efficient and accurate technique is emphasized. A companion volume brings together several analytical investigations, based on advanced compu tational mechanics methods, for correlation of the experimental data as well as eval uation of the effects of residual stress on rail integrity.
