The aim of this paper is to review existing publicly available and open artificial intelligence
(AI) oriented datasets in different domains and subdomains of the railway sector. The …

This paper presents a novel framework for the discrete modeling of the large-scale triaxial
test of rock clasts, considering both the realistic particle shapes and veritable flexible …

In any DEM simulation, the chosen particle shape will greatly influence the simulated
material behaviour. For a specific material, eg railway ballast, it remains an open question …

Across the world, ballasted railway tracks are utilised extensively due to their cost efficiency,
ease of drainage, and capacity to withstand cyclic imposed loadings from heavy trains. In …

Abstract Electric Arc Furnace steel slag aggregate has potential for wider application in
railway infrastructures. Nonetheless, its use in ballast layers, as an alternative to natural …

Open research data practices are a relatively new, thus still evolving part of scientific work,
and their usage varies strongly within different scientific domains. In the literature, the …

Digital image processing has become the mainstream method for measuring aggregate
morphologies. However, the results of the image method are seriously affected by the laying …

Railway ballast layer is an indispensable component of railway transport. Ballast
morphology plays an important effect in ballast-sleeper interaction and the durability of …

Railway ballast affected by heavy cyclic loading degrades and spreads resulting in an
uncomfortable transportation caused by undesirable vibrations. Restoring a well sorted track …

Spherical harmonics (SH) have been extensively used as a basis for analyzing the
morphology of particles in granular mechanics. The use of SH is facilitated by mapping the …
