Granular matter is ubiquitous in nature and is present in diverse forms in important
engineering, industrial and natural processes. Particle-based computational modelling has …

Modeling of heterogeneous materials and media is a problem of fundamental importance to
a wide class of phenomena and systems, ranging from condensed matter physics, soft …

The discrete element method (DEM) is used to model granular materials and analyse a wide
range of related applications. However, accurate predictions can only be made if the input …

Definitions of soil particle sphericity, roundness and roughness have existed since at least
the 1930s. In the 1950s, charts of typical sphericity and roundness values were developed to …

Many problems in geotechnical engineering involve large movements or rotations,
examples include natural processes such as landslides, and man-made processes such as …

Particle morphological features at different scale levels hold the key to understanding the
geological origin and mechanical behaviour of natural sands. In this context, it is necessary …

This paper presents a new three-dimensional (3D) contact model incorporating rolling and
twisting resistances at inter-particle contact, which can be introduced into the discrete …

The particle micromorphology created by geological processes is an essential characteristic
in determining the mechanical properties of natural sands. Based on micro X-ray computed …

The physical and mechanical performance of concrete is inherently dependent on
aggregate morphology including the general shape at coarse-scale, the local roundness at …

Particle morphology plays a key role in affecting physical and mechanical behaviors of
granular media. While various mathematical approaches and shape descriptors have been …
