Limit current density in 2 D metallic granular packings
نویسندگان
چکیده
The electrical properties 2D of packed metallic pentagons have been studied. The characterization of such metallic pentagon heaps (like i − V measurements) has been achieved and has allowed to point out two distinct conduction regimes. They are separated by a transition line along which the system exhibits a memory effect behavior due to the irreversible improvement of electrical contacts between pentagons (hot spots). A limit current density has been found.

We describe the contact network of granular packings by a frustrated lattice gas that contains steric frustration as esential ingredient. Two transitions are identified, a spin glass transition at the onset of Reynolds dilatancy and at lower densities a percolation transition. We describe the correlation functions that give rise to the singularities and propose some dynamical experiments. Let u...
متن کاملPacking of compressible granular materials
3D computer simulations and experiments are employed to study random packings of compressible spherical grains under external confining stress. In the rigid ball limit, we find a continuous transition in which the stress vanishes as (straight phi-straight phi(c))(beta), where straight phi is the (solid phase) volume density. The value of straight phi(c) depends on whether the grains interact vi...
متن کاملDisordered strictly jammed binary sphere packings attain an anomalously large range of densities.
Previous attempts to simulate disordered binary sphere packings have been limited in producing mechanically stable, isostatic packings across a broad spectrum of packing fractions. Here we report that disordered strictly jammed binary packings (packings that remain mechanically stable under general shear deformations and compressions) can be produced with an anomalously large range of average p...
متن کاملFootprints in sand: the response of a granular material to local perturbations.
We experimentally determine ensemble-averaged responses of granular packings to point forces, and we compare these results to recent models for force propagation in a granular material. We use 2D granular arrays consisting of photoelastic particles: either disks or pentagons, thus spanning the range from ordered to disordered packings. A key finding is that spatial ordering of the particles is ...
متن کاملJamming V: Jamming in two-dimensional packings
We investigate the existence of random close and random loose packing limits in twodimensional packings of monodisperse hard disks. A statistical mechanics approach— based on several approximations to predict the probability distribution of volumes— suggests the existence of the limiting densities of the jammed packings according to their coordination number and compactivity. This result has im...
