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."
