Dilatancy is often considered a unique function of the stress ratio η= q/p′, in terms of the
triaxial stress variables q and p′. With this assumption, the direction of plastic flow is …

The model of static hypothesis is not readily available for granular material treated as a
collection of particles. Unlike other types of material, the internal stresses in a granular …

A discrete element modeling of granular material was carried out using a 3D spherical
discrete model with a rolling resistance, in order to take into account the roughness of …

Tool‐rock interaction processes can be classified as indentation or cutting depending on the
direction of motion of the tool with respect to the rock surface. The modes of failure induced …

Purpose–To use distinct element simulation (PFC2D) to investigate the relationships
between microparameters and macroproperties of the specimens that are modeled by …

This study on discrete element modelling of tool-rock interaction focuses on establishing
scaling laws between the phenomenological parameters of a material and the properties of …

Granular materials are typically characterized by complex structure and composition.
Continuum modeling, therefore, remains the mainstay for describing properties of these …

Test results for concrete loaded at high strain rates in tension, obtained with a new
experimental technique, and numerical simulations of those experiments by discrete …

A discrete element method (DEM) is used to model both the dynamic and non-linear
behaviour of rocks, with a particular focus on a Villejust quartzite and a MB50 type …

Gradient theories, as a regularized continuum mechanics approach, have found wide
applications for modeling strain localization failure process. This paper presents a second …
