The mechanical and rheological behaviour of particulate and granular assemblies is
significantly influenced by the shape of their individual particles. We present a code that …

Despite the significant progresses in discrete-based numerical studies of granular materials,
most efforts have been placed in the study of large deformation problems and there are …

Scale effects and the influence of surface roughness were investigated on the contact
behavior of glass specimens of the grain-grain, grain-block and block-block configurations …

In the rough surface contact research, the real contact area has long been the primary focus,
however, the details of contact spots, such as the size, morphology, and distribution which …

Recycled rubber in granulated form is a promising geosynthetic material to be used in
geotechnical/geo-environmental engineering and infrastructure projects, and it is typically …

Abstract In the Discrete Element modelling of soils, the micromechanical behaviour at
contacts has often been considered to have a minor influence on the macromechanical …

This contribution proposes a methodology to measure the surface roughness of granular
materials using the Gaussian filter. Artificially generated rough surfaces with known root …

In recent years, bio-inspired burrowing robots and other intruder problems in granular media
have attracted significant attention. Many of these, especially related to traditional …

The impact of non-Gaussian height distribution on the real contact area evolution of elastic,
frictionless and non-adhesive contact is studied. The Weibull probability function is used to …

The contact problem of soft-rigid interfaces is investigated in this study performing
micromechanical-based experiments on sand (rigid) grains sliding against granulated (soft) …
