The paper summarises damage tolerance investigations on railway rails which the authors have carried out in the context of the German-French joint project NOVUM (novel methods for quantitative prediction of rail performance at increased service loads) (Girardi L, Heyder R, Dider L, Boulanger D. IDR2-NOVUM promises lower rail maintenance costs. Railway Gazette Int 2005;(July):439-41(1)). The investigations include the determination of the crack driving force as a function of the various loading components a rail is subjected to and the simulation of residual lifetime. Features such as the local load input at the rail-wheel interface, dynamic effects and statistical aspects of crack resistance are explicitly taken into account.
