Modelling ballast behaviour using a three-dimensional polyhedral Discrete Element method
Résumé
The deterioration of the railway track under a large number of train runnings, in particular the settlement mechanism of the ballast layer or the lateral buckling of track, remains insufficiently known. In order to study the behaviour of ballast layer a three-dimensional Discrete Element Method (DEM), based on the Non Smooth Contact Dynamic (NSCD) approach has been developed.
