Estimation of service life of rail welding joint concerning thermal stresses

Last updated on 12 October 2012 5:58

Nowadays, rolling contact fatigue failure and rail welds bending fatigue failure are two main factors with regards to which a lot of track maintenance work are carried out. In particular, the standard of continuous welded rails (CWR) renewal is practically decided by the rail welds bending fatigue. The authors has...
