A long-standing issue in the area of granular media is the tail of the force distribution, in particular, whether this is exponential, Gaussian, or even some other form. Here we resolve the issue for the case of the force network ensemble in two dimensions. We demonstrate that conservation of the total area of a reciprocal tiling, a direct consequence of local force balance, is crucial for predicting the local stress distribution. Maximizing entropy while conserving the tiling area and total…

The force network ensemble for granular packings
For packings of hard but not perfectly rigid particles, the length scales that govern the packing geometry and the contact forces are well separated. This separation of length scales is explored in
Force balance in canonical ensembles of static granular packings
We investigate the role of local force balance in the transition from a microcanonical ensemble of static granular packings, characterized by an invariant stress, to a canonical ensemble. Packings in
Stress fluctuations in granular force networks
The heterogeneous force networks in static granular media are distinguished from other network structures in that they must satisfy constraints of mechanical equilibrium on every vertex/grain. Here
Force network ensemble for the triangular lattice: a tale of tiles.
Large local stresses obey Gaussian statistics, in sharp contrast to the common belief that exponential force statistics are characteristic for granular materials, and is robust to changes in contact network including disordered networks and finite friction coefficient.
Contact forces distribution for a granular material from a Monte Carlo study on a single grain
The force network ensemble is one of the most promising statistical descriptions of granular media, with an entropy accounting for all force configurations at mechanical equilibrium consistent with
Cavity method for force transmission in jammed disordered packings of hard particles.
A mean-field theory is developed for jammed disordered packings based on the consideration of the contact network as a random graph where the force transmission becomes a constraint satisfaction problem, and a new signature of jamming is found in the small force behavior.
A master equation for the probability distribution functions of forces in soft particle packings.
By numerically determining the transition rates for all changes of contacts and gaps, this work forms a Master equation for the PDFs of forces, where the insight one gets from the Transition rates is striking: the mean change of forces reflects non-affine system responses, while their fluctuations obey uncorrelated Gaussian statistics.
Dynamics of correlated forces in lattice model of granular solids near jamming.
The model appears to approach point J at a finite temperature, at which various timescales diverge without an obvious corresponding divergence in the correlation length of some static order parameter, suggesting that this lattice model exhibits a hallmark of a dynamical glass transition.


Ensemble theory for force networks in hyperstatic granular matter.
A general formulation of this force network ensemble is given, and the general expression for the force distribution P(f) is derived, which touches upon the deep question of how network statistics is related to the underlying network structure.
Force network ensemble: a new approach to static granular matter.
An ensemble approach for force distributions in static granular packings is developed. This framework is based on the separation of packing and force scales, together with an a priori flat measure in
Tail of the contact force distribution in static granular materials.
The findings unambiguously show that, in the ensemble approach, the force distributions decay much faster than exponentially: P(f) approximately exp(-cf(alpha)}) , with alpha approximately 2.0 for 2D systems, and alpha approximately 1.7 for 3D systems.
Force distributions in three-dimensional compressible granular packs.
It is found that the degree of deformation of individual grains plays a large role in determining the form of this distribution of normal contact forces, P(F), at the bottom boundary of static three-dimensional packings of compressible granular materials.
We report on systematic measurements of the distribution of normal forces exerted by granular material under uniaxial compression onto the interior surfaces of a confining vessel. Our experiments on
Model for force fluctuations in bead packs.
This model reproduces many aspects of the force distribution observed both in experiment and in numerical simulations of sphere packings, including exact results for certain contact angle probability distributions.
Entropy and temperature of a static granular assembly: an ab initio approach.
A statistical framework for static assemblies of deformable grains is constructed which parallels that of equilibrium statistical mechanics but with a conservation principle based on the mechanical stress tensor, leading to a well-defined granular temperature and the equivalent of the Boltzman distribution for ensembles of grain packings.
Force distributions in three-dimensional granular assemblies: effects of packing order and interparticle friction.
Under uniaxial compression it is found that the form for the probability distribution of normal forces between particles does not depend strongly on crystallinity or interparticle friction.
Force distributions in a triangular lattice of rigid bars.
It is found that for periodic boundary conditions corresponding to isotropic compressive stress, the probability distribution for single-contact forces decays faster than exponentially, and a broader tail emerges in the force distribution, becoming a pure exponential in the limit of infinite lattice size and infinitely strong anisotropy.
