Wet Granular Materials [PDF]

Advances in Physics, 2006
Most studies on granular physics have focused on dry granular media, with no liquids between the grains. However, in geology and many real world applications (e.g., food processing, pharmaceuticals, ceramics, civil engineering, constructions, and many ...

Ratcheting of granular materials [PDF]

Physical Review Letters, 2003
We investigate the quasi-static mechanical response of soils under cyclic loading using a discrete model of randomly generated convex polygons. This response exhibits a sequence of regimes, each one characterized by a linear accumulation of plastic ...

Flow of wet granular materials [PDF]

Physical Review Letters, 2004
The transition from frictional to lubricated flow of a dense suspension of non-Brownian particles is studied. The pertinent parameter characterizing this transition is the Leighton number $Le = \frac{\eta_s \dot{\gamma}}{\sigma}$, which represents the ...

Thermal shakedown in granular materials with irregular particle shapes [PDF]

Scientific Reports
Granular materials with irregular particle shapes undergo a myriad of temperature variations in natural and engineered systems. However, the impacts of cyclic temperature variations on the mechanics of granular materials remain poorly understood ...

Scaling properties of granular materials [PDF]

Physical Review E, 2002
Given an assembly of viscoelastic spheres with certain material properties, we raise the question how the macroscopic properties of the assembly will change if all lengths of the system, i.e. radii, container size etc., are scaled by a constant.

Packing of Compressible Granular Materials [PDF]

Physical Review Letters, 2000
3D Computer simulations and experiments are employed to study random packings of compressible spherical grains under external confining stress. Of particular interest is the rigid ball limit, which we describe as a continuous transition in which the ...

Dynamic compaction of granular materials. [PDF]

Proc Math Phys Eng Sci, 2013
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.

Cohesion-controlled granular material [PDF]

Physical Review E, 2020
We present a simple method to prepare a granular material with a controlled cohesion between particles. The granular material is made of spherical glass beads coated with a polyborosiloxane polymer. This material is proved to be stable in time and nonsensitive to temperature and humidity.

Liquid migration in flowing granular materials [PDF]

EPJ Web of Conferences, 2021
In partially wet granular beds, liquid migrates between particles due to collisions and contacts. This, in turn, influences the flow behaviour of the granular bed.

Mesoscale inertial transition in granular materials [PDF]

EPJ Web of Conferences, 2021
Granular assemblies can experience complex failure patterns along a given loading path, with a distribution of ephemeral inertial events marked by local outbursts in kinetic energy.
