Nonlinear finite element analysis for structural capacity of railway prestressed concrete sleepers with rail seat abrasion

Analysis of the Influence of Cracked Sleepers under Static Loading on Ballasted Railway Tracks

The principal causes of cracking in prestressed concrete sleepers are the dynamic loads induced by track irregularities and imperfections in the wheel-rail contact and the in-phase and out-of-phase track resonances. The most affected points are the mid-span and rail-seat sections of the sleepers. Central and rail-seat crack detection require visual inspections, as legislation establishes, and i...

Investigation on simulation of train loading on prestressed concrete sleepers

Railway concrete sleepers have been developed and utilized in railway industry for over 50 years. Cyclic loading because of vibration on sleepers due to the train loading and the velocity of train itself and also a small percentage of bad wheels, can eventually lead to a crack network and failure of component. The objective of this study is to investigate the load carrying capacity of the selec...
