Abstract
This article presents fatigue tests conducted on aging continuous welded rails (CWR) in order to estimate the service life of the rails. This was done in order to prepare a dynamic stress analysis model for welded joints with boltholes. Such an analysis is useful for re-estimating rail life due to reduced vehicle weight and better jointures that operators have experienced in recent years. This also included the anticipated result of extending the period of replacement for such rails. The tests conducted used a beam model that allowed for the analysis of dynamic wheel/rail contact and interface forces in addition to a solid model that was used to analysis stress fields based on those forces. Dynamic stress analysis indicated that the specified model's testing is valid as checked against field tests. The extension of service life for CWRs was deemed safe by the test with the proviso that such welds would need to be accompanied by the grinding of surface irregularities.
