Interparticle Friction in Granular Ceramic Materials
The frictional behaviour of dry ceramic materials in the form of spherical beads, sand and spray dried powders has been studied.

Granular materials in geotechnical engineering is generally considered to be mixtures of clay, sand, and gravel that commonly appear in slopes, valleys, or river beds, and they are especially used for the construction of earth-rock-filled dams.

Viscoelasticity of granular materials
Abstract In a former work (V.T. Granik and M. Ferrari (1993), Microstructural mechanics of granular media, Mech. Mater. 15, 301–322) a micromechanical theory for elastic granular media was deduced on the basis of the identification of the constituent grains with the nodes of a Bravais lattice.

Microstructural anisotropy as the origin of dilatancy [PDF]
Dilation in sheared granular materials has been widely observed, yet its micromechanical origins remain debated. Using discrete element method (DEM) simulations of slow granular flows, we find that grain rearrangements occur intermittently, alternating ...

Two-phase densification of cohesive granular aggregates [PDF]
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.

Remarks on Constitutive Modeling of Granular Materials
In this paper, we provide a brief overview of certain fundamental concepts which can be used to derive constitutive relations for the stress tensor of granular materials. These include concepts such as dilatancy, cohesion, yield criterion, shear banding,

Coupling between rotational and translational motions of a vibrated polygonal disk
We investigate experimentally the dynamics of a single polygonal disk (regular n -gon with 3 ⩽ n ⩽ 8) confined in a closed container under vertical vibrations against gravity.

Dynamic compaction of granular materials. [PDF]
An Eulerian hyperbolic multiphase flow model for dynamic and irreversible compaction of granular materials is constructed. The reversible model is first constructed on the basis of the classical Hertz theory. The irreversible model is then derived in accordance with the following two basic principles.

Jamming transition in emulsions and granular materials
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 ...
