Characterization of Contact Parameters for Discrete Element modelling of Swiss Railway Ballast Open
Ballast is an integral part of the rail network which helps for effective load transfer between the rails and subgrade.Modelling of ballast is often carried out using finite element methods which considers ballast as a continuous material …

Estimation of the dynamic stiffness of railway ballast over a wide frequency range using the discrete element method Open
Ballast is an integral part of railways, serving as a load transfer medium between the rails and the subgrade. In analytical modeling of track dynamics, ballast is idealized as a spring with constant stiffness at all excitation frequencies…

Characterisation of contact parameters of sand grains to be used for discrete element modelling Open
Discrete element method (DEM) is a numerical technique that models the material as a combination of discrete particles which interact with each other through the contacts springs. While modelling soil in finite element method (FEM), approx…
