Slow relaxation and compaction of granular systems.
Granular materials are of substantial importance in many industrial and natural processes, yet their complex behaviours, ranging from mechanical properties of static packing to their dynamics, rheology and instabilities, are still poorly understood. Here we focus on the dynamics of compaction and its 'jamming' phenomena, outlining recent statistical mechanics approaches to describe it and their...

متن کاملProbing slow dynamics of consolidated granular multicomposite materials by diffuse acoustic wave spectroscopy.
The stiffness of a consolidated granular medium experiences a drop immediately after a moderate mechanical solicitation. Then the stiffness rises back toward its initial value, following a logarithmic time evolution called slow dynamics. In the literature, slow dynamics has been probed by macroscopic quantities averaged over the sample volume, for instance, by the resonant frequency of vibratio...
متن کاملFrustration and slow dynamics of granular packings
Dynamical processes in granular media show fascinating behavior @1–4#. The particular role of disorder and fluctuations in granular dynamics has led several authors @1,5–7# to propose an analogy to frustrated statistical systems such as spin glasses @8#. Recently a frustrated lattice gas model has been introduced to describe static and dynamic properties of granular materials @9#. This microsco...
متن کاملDynamics of Granular Systems
Granular media are dissipative systems. The collisions between the grains are inelastic and therefore energy is intrinsically lost within the system while it is in motion. In order to explore some of the fundamental resulting effects on the statistical properties of such systems, let us idealize a granular medium by a set of N spherical particles, all being identical and having only the exclusi...
