Two-phase densification of cohesive granular aggregates [PDF]
, 2001 When poured into a container, cohesive granular materials form low-density, open granular aggregates. If pressed upon with a ram, these aggregates densify by particle rearrangement.

Jamming transition in emulsions and granular materials
, 2005 We investigate the jamming transition in packings of emulsions and granular materials via molecular dynamics simulations. The emulsion model is composed of frictionless droplets interacting via nonlinear normal forces obtained using experimental data ...

Multiple shear bands in granular materials
EPJ Web of Conferences, 2017 The transition regime from quasi-static to dynamic shear regime is studied by discrete element method (DEM) and by means of a mesoscopic model. We show that at moderate shear rate multiple shear bands appear which eventually appear as a continuous shear ...

The Experimental Stress – Strain Rate Relationship of Granular Materials [Translated]†
KONA Powder and Particle Journal, 2014 The flow of granular materials is important in the field of material handling. However, there are many unknown factors associated with the analysis of these flows.

3D MULTI-SCALE SEGMENTATION OF GRANULAR MATERIALS
Image Analysis and Stereology, 2011 On a microscopic scale, a pyrotechnic material is made of a polymer matrix containing grains with different sizes and shapes. Its physical behaviour can be predicted by homogenization.

How granular materials deform in quasistatic conditions [PDF]
, 2009 Based on numerical simulations of quasistatic deformation of model granular materials, two rheological regimes are distinguished, according to whether macroscopic strains merely reflect microscopic material strains within the grains in their contact ...

Numerical simulation of cementitious granular materials
Science and Engineering of Composite Materials, 2012 A new numerical approach was developed to study the mechanical properties of cementitious granular materials. At first, an ellipsoid based method was developed to generate aggregate particles of arbitrary shape.

Velocity correlations in granular materials
, 1998 A system of inelastic hard disks in a thin pipe capped by hot walls is studied with the aim of investigating velocity correlations between particles. Two effects lead to such correlations: inelastic collisions help to build localized correlations, while ...

Two scenarios for avalanche dynamics in inclined granular layers
, 2005 We report experimental measurements of avalanche behavior of thin granular layers on an inclined plane for low volume flow rate. The dynamical properties of avalanches were quantitatively and qualitatively different for smooth glass beads compared to ...
