This tool is in use for research projects on traffic induced vibration propagation and was extended to fatigue analysis of continuous concrete rail tracks, called slab tracks. With this paper a numerical model for the dynamic behaviour of a rail-track under traffic load has been presented, which is well capable of simulating the deformations and the stress distribution of the slab track. The presented comparison of computational results with data from field investigations show the necessity of taking the pre-strain dependent dynamic behaviour of the existing cracks into account. To obtain more realistic time histories for the stress distribution within the track further refinements must be undertaken at the model to include the effects of vehicle dynamics. Bergmann showed the fatigue response of the slab track being very sensitive to numerous parameters. Thus, a realistic prediction of the track vibrations and stress distribution is essential for future life cycle analysis.
