Systems of randomly packed, macroscopic elements, from jammed spherical grains to tangled long filaments, represent a broad class of disordered meta-materials with a wide range of applications and manifestations in nature. A `bird nest' presents itself at an interface between hard round grains described by granular physics to long soft filaments, the center of textile material science. All of these randomly packed systems exhibit forms of self assembly, evident through their robust packing…

Cohesion of bird nests
One striking difference between aggregates of flexible frictional fibres and other granular materials like rigid spheres is the effective cohesion of their assembly. While glue or capillary bridges
Bespoke particle shapes in granular matter
Among granular matter, one type of particle has special properties. Upon being assembled in disordered configurations, these particles interlock, hook, almost braid, and – surprisingly, considering
Emergence of structure in columns of grains and elastic loops.
TLDR
It is found that higher friction leads to larger stable grain-grain and grain-loop contact angles resulting in a simple function for the frictional critical spacing, which depends linearly on friction to first order.
Fast and accurate computation of interactions between linear fiber segments
TLDR
A fast, efficient and effective computational methodology to estimate such interactions which can be coupled with Hamiltonian mechanics to simulate the behavior of fibrous systems is offered.
A Modeling Framework for Jamming Structures
Jamming is a structural phenomenon that provides tunable mechanical behavior. A jamming structure typically consists of a collection of elements with low effective stiffness and damping. When a

A Discrete Element Method model for frictional fibers
We present a Discrete Element Method algorithm for the simulation of elastic fibers in frictional contacts. The fibers are modeled as chains of cylindrical segments connected to each other by springs
Continuous Binder-Free Fibers of Pure Imogolite Nanotubes
TLDR
Interestingly, in the absence of a matrix phase, a degree of misorientation appears to improve load transfer between the individual INTs within the porous fiber, likely due to an increase in the number of interparticle contacts.
Two-stage athermal solidification of semiflexible polymers and fibers.
TLDR
The character of the energy and pressure increases above φJ(θ0) can be characterized via chains' effective aspect ratio αeff, which is similar to that observed in systems composed of straight fibers.

Emergent Strain Stiffening in Interlocked Granular Chains.
TLDR
This study suggests that theories normally confined to the realm of polymer physics at a molecular level can be used to explain phenomena at a macroscopic level in granular chain packings, with practical implications for the design of new materials, the textile industry, and biology.
The Packing of Granular Polymer Chains
TLDR
Using x-ray tomography, it is found that long chains pack into a low-density structure whose mechanical rigidity is mainly provided by the backbone, and close similarities are uncovered between the packing of chains and the glass transition in polymers.
Compaction of rods: relaxation and ordering in vibrated, anisotropic granular material.
TLDR
It is found that the orientational ordering process is reflected in a characteristic, steep rise in the local packing fraction, at any given height inside the packing, which is initiated at the container walls and proceeds inward.
Strain stiffening in random packings of entangled granular chains.
TLDR
Random packings of granular chains are presented as a model system to investigate the contribution of entanglements to strain stiffening, in which the effective stiffness of the material increases with strain, similar to many polymer materials.
Effect of aspect ratio on the mechanical behavior of packings of spheroids
Random packings of spheres and spherocylinders simulated by mechanical contraction.
TLDR
A simulation technique for creating dense random packings of hard particles is introduced, particularly suited to handle particles of different shapes, and Comparisons between the equilibrium phase diagram for hard spherocylinders and the densest possible amorphous packings have interesting implications on the crystallization of sphero cylinders as a function of aspect ratio.

TLDR
The current understanding of the transition to jamming and the nature of the jammed state for disordered packings of particles that act through repulsive contact interactions and are at zero temperature and zero shear stress is reviewed.
Entangled granular media.
TLDR
The geometrically induced cohesion of ensembles of granular "u particles" that mechanically entangle through particle interpenetration is studied to reveal that optimal strength results from competition between packing and entanglement.
