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 …

Granular materials consist of macroscopic grains, interacting via contact forces, and
unaffected by thermal fluctuations. They are one of a class systems that undergo jamming, ie …

Granular flows are omnipresent in nature and industrial processes, but their rheological
properties such as apparent friction and packing fraction are still elusive when inertial …

The mechanical behaviors of granular soils at different initial densities and confining
pressures in the drained and undrained triaxial tests are investigated micromechanically by …

Soft, disordered, micro-structured materials are ubiquitous in nature and industry, and are
different from ordinary fluids or solids, with unusual, interesting static and flow properties …

This paper aims to study the shear behavior of granular matter by DEM simulations.
Granular samples are prepared by automatic clump generation algorithm to create particles …

Physical experiments can characterize the elastic response of granular materials in terms of
macroscopic state variables, namely volume (packing) fraction and stress, while the …

Particle shape plays an important role in both the micro and macro scales responses of a
granular assembly. This paper presents a systematic way to interpret the shape effects of …

Ballasted tracks are the commonly used railway track systems with constant demands for
reducing maintenance cost and improved performance. Elastic layers are increasingly used …

This article presents an analysis of the shear strength of numerical samples composed of
polyhedra presenting a grain size dispersion. Previous numerical studies using, for instance …
