Railway ballast performance is dictated by a complex mix of mechanical properties. These
effect its performance at the particle level for example in terms of particle degradation, but …

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 …

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 …

Blocky rock and stone structures (such as jointed rocks mass, masonry structures and
railway ballast) are often submitted to dynamic effects. Their mechanical behaviour can be …

High-speed railways are very important in global transportation. However, the railway
subgrade is significantly affected by the environment due to its exposure to the atmosphere …

Transport by rail is an efficient way of moving goods and people while managing problems
such as congestion and the consequences on the environment. The relatively low energy …

For complex shaped materials, computational efficiency and accuracy of DEM models are
usually opposing requirements. In the literature, DEM models of railway ballast often use …

Despite ongoing research, the parametrisation of a DEM model is a challenging task, as it
depends strongly on the particle shape representation used, particle-particle contact law …

The conventional engineering design of threaded fasteners applies a linear model
determining axial force from fastening torque and was found to be applicable only for …

In this dissertation, a coupled discrete–finite element method model was created to
modelthe loads on machines that interact with crushed rock aggregates. A further aim of the …
