TLDR
In this article, a unified, densely correlated understanding of granular physics emerges as a result of these phenomena ordered and explained employing a single framework, which is a continuum mechanical theory constructed to qualitatively explain granular phenomena.Abstract:
{\sc gsh} is a continuum mechanical theory constructed to qualitatively account for a broad range of granular phenomena. To probe and demonstrate its width, simple solutions of {\sc gsh} are related to granular phenomena and constitutive models, including (i) for vanishing shear rates: static stress distribution and propagation of elastic waves; (ii) at slow rates: critical state, shear band, the models of hypoplasticity and barodesy; (iii) at higher rates: the MIDI-model, rapid dense flow in the Bagnold regime. A unified, densely correlated understanding of granular physics emerges as a result of these phenomena ordered and explained employing a single framework.read more

Continuum Mechanical Modeling of Dry Granular Systems: From Dilute Flow to Solid-Like Behavior
TL;DR: In this paper, the authors developed a granular hydrodynamic model which covers the three principal regimes observed in granular systems, i.e. the dilute flow, the dense flow and the solid-like regime.

Creep and fluidity of a real granular packing near jamming
TL;DR: In this paper, the internal dynamical processes taking place in a granular packing below yield stress were analyzed under the scope of a visco-elastic model introducing an internal "fluidity" variable.

Experiments on a Gravity-Free Dispersion of Large Solid Spheres in a Newtonian Fluid under Shear
TL;DR: In this article, a large number of spherical grains of diameter D = 0.13 cm were sheared in Newtonian fluids of varying viscosity (water and a glycerine-water-alcohol mixture) in the annular space between two concentric drums.

Physics of Liquid Crystals
TL;DR: In this paper, the authors describe the story of the recent developments and the future perspectives in physics of liquid crystals, especially focusing on the contributions by Japanese research groups for the last decade, and present new subjects unmentioned in the book.

Soil Behaviour and Critical State Soil Mechanics
TL;DR: In this article, the basic ingredients of a family of simple elastic-plastic models of soil behaviour are described and used in numerical analyses. But the models on which this book concentrates are simple, understanding of these will indicate the ways in which more sophisticated models will perform.

On dense granular flows.
TL;DR: A quantitative comparison between data coming from different experiments in the same geometry identifies the robust features in each case and a transverse analysis of the data across the different configurations allows to identify the relevant dimensionless parameters, the different flow regimes and to propose simple interpretations.
