This is a monograph written for the young and advanced researcher who is entering the field of wet granular matter and keen to understand the basic physical principles governing this state of soft matter. It treats wet granulates as an instance of a ternary system, consisting of the grains, a primary, and a secondary fluid. After addressing wetting phenomena in general and outlining the basic facts on dry granular systems, a chapter on basic mechanisms and their effects is dedicated to every region of the ternary phase diagram. Effects of grain shape and roughness are considered as well. Rather than addressing engineering aspects such as existing books on this topic do, the book aims to provide a generalized framework suitable for those who want to understand these systems on a more fundamental basis.

Focussing on the basic mechanics and underlying physics of granular material, Mechanics of Granular Matter starts with an introduction to contact mechanics of individual particles before moving on to a discussion of the structure of force chain networks and the influence on bulk mechanical properties of granular solids and granular flows. Furthermore, a preliminary multi scale framework is proposed for the nonlinear mechanics and strain localization in granular materials.

Avalanches, mudflows and landslides are common and natural phenomena that occur in mountainous regions. With an emphasis on snow avalanches, this book provides a survey and discussion about the motion of avalanche-like flows from initiation to run out. An important aspect of this book is the formulation and investigation of a simple but appropriate continuum mechanical model for the realistic prediction of geophysical flows of granular material.

Powders have been studied extensively because they arise in a wide variety of fields, ranging from soil mechanics to manufacture of pharmaceuticals. Only recently, however, with the deepening understanding of fractals, chaos, 1/f noise, and self-organization, has it been useful to study the mechanical properties of powders from a fundamental physical perspective. This book collects articles by some of the foremost researchers in the field, including chapters on: the role of entropy in the specification of a powder, by S.F. Edwards (Cambridge); discrete mechanics, by P.K. Haff (Duke); computer simulations of granular materials, by G.C. Barker (Norwich); pattern formation and complexity in granular flow, by R.P. Behringer and G.W. Baxter (Duke); avalanches in real sand piles, by A. Mehta (Birmingham); micromechanical models of failure, by M.J. Adams (Unilever) and B.J. Briscoe (Imperial College); mixing and segregation in particle flows, by J. Bridgwater (Birmingham); and hard-sphere colloidal suspensions, by P. Bartlett (Bristol) and W. van Megen (Melbourne).

This monograph covers phenomena of deformation and machining of granular media: macroscopic particles of different size, shape, and surface properties which typically exhibit behavior similar to fluids, as well as the behavior of solids under deformation. The book analyses the behavior of granular media in soils, rocks and stones, metals and various synthetic materials, presenting a theoretical description, applications and understanding of basic phenomena in granular matter.

Granular flows and segregation are important in a wide range of industrial and geological situations varying from mixing powders and formulation for pharmaceutical industries to landslides. The goal of this work is to better understand both the flow dynamics and the segregation in granular materials using a prototypical system---a quasi-2D rotating tumbler. Both dry granular matter and wet granular matter (slurries) are considered. Particle Image Velocimetry (PIV) coupled with Particle Tracking Velocimetry (PTV) is used to measure the dynamics in the flowing layer to investigate the effect of the interstitial fluid. Under slurry conditions the flowing layer thickness and the angle of repose are higher than the dry counterpart for the same sized beads tumbled at the same angular velocity. However, the surface velocity and shear rate are smaller when the interstitial fluid is a liquid rather than air. The velocity profile is nearly linear throughout the layer except for a region near the fixed bed where the velocity profile is logarithmic. Experiments on granular segregation in a circular tumbler reveal that for particle size and density combinations where percolation and buoyancy both contribute to segregation, either radial streaks or a "classical" core can occur, depending on the particle size ratio. Mixing is observed instead of segregation when the denser beads are larger than the lighter beads so that the ratio of particle sizes is greater than the ratio of particle densities. Changes in the tumbler shape introduce chaos in the system and causes segregation patterns to differ significantly in shape. Regardless of the differences in the shape of segregation pattern for these tumblers, the final mixing efficiency predominantly depends on the particle parameters.
