Available in PDF, EPUB and Kindle. Book excerpt: 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).

Available in PDF, EPUB and Kindle. Book excerpt: This introductory text develops the fundamental physics of the behavior of granular materials. It covers the basic properties of flow, friction, and fluidization of uniform granular materials; discusses mixing and segregation of heterogeneous materials (the famous "brazil-nut problem"); and concludes with an introduction to numerical models. The presentation begins with simple experiments and uses their results to build concepts and theorems about materials whose behavior is often quite counter-intuitive; presenting in a unified way the background needed to understand current work in the field. Developed for students at the University of Paris, the text will be suitable for advanced undergraduates and beginning graduates; while also being of interest to researchers and engineers just entering the field.

Download or read book Mechanical Properties of Granular Materials Using Nanoindentation and Modeling with Distinct Element Method written by Amal Kumar Dutta and published by . This book was released on 2006 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mechanics of granular material is an important issue that governs many geotechnical engineering applications. Two types of particles having similar particle size, but different shape are used in this research to evaluate the role of particle morphology on the physical properties of its assemblage. Experimentation of 1-D compression behavior at constant axial strain rate under laterally confined conditions is performed for these two particulate materials and the behavior of the stress path is analyzed in relation to the initial material packing and physical characteristics of the granules. The behavior of granular assemblages under imposed loading conditions are also evaluated by analyzing the macro and micro level morphological changes (in terms of shape and size distribution) resulting from 1-D compression tests. Various experimental procedures and techniques are employed for characterizing the size and shape aspect of these particles. The mechanical properties (hardness, modulus, and time dependent creep parameters) of the individual particles are determined and analyzed using nanoindentation technique. Nanoindentation has emerged recently as a powerful tool for precise measurements of mechanical properties of materials. Considering its potential applicability in the broad area of micromechanics associated with granular materials, an in-depth study of its application is performed. Since a rigorous study of the nanoindentation technique for finite size particles has not been done to date, initial testing for developing appropriate experimental and interpretation procedures required testing reference material such as fused quartz and novel composite materials to gain additional insight and experience. For this reason, besides granular materials, the changes in mechanical properties for structured materials (blended single wall carbon nanotube-epoxy composite specimens) are also included in this research. The micromechanical analysis of granular assembly using computer simulation through the program PFC2 [superscript D] (2-Dimensional Particle Flow Code), an application of Distinct Element Method (DEM) is also performed. The material micro-properties such as particle shear stiffness and normal stiffness values are assigned from the nanoindentation test results for the two granular materials. The particle contact behavior, nature of force chain structure, and uniformity of deformation associated with 1-D compression on granular materials having different shape and mechanical properties are analyzed.

Download or read book Built on Sand written by Etienne Guyon and published by MIT Press. This book was released on 2020-03-31 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explaining the science contained in a simple assembly of grains—the most abundant form of matter present on Earth. Granular media—composed of vast amounts of grains, consolidated or not—constitute the most abundant form of solid matter on Earth. Granular materials assemble in disordered configurations scientists often liken to a bag of marbles. Made of macroscopic particles rather than molecules, they defy the standard scheme of classification in terms of solid, liquid, and gas. Granular materials provide a model relevant to various domains of research, including engineering, physics, and biology. William Blake famously wished “To See a World in a Grain of Sand”; in this book, pioneering researchers in granular matter explain the science hidden behind simple grains, shedding light on collective behavior in disordered settings in general. The authors begin by describing the single grain with its different origins, shapes, and sizes, then examine grains in piled or stacked form. They explain the packing fraction of granular media, a crucial issue that bears on the properties displayed in practical applications; explore small-scale deformations in piles of disordered grains, with particular attention to friction; and present theories of various modes of disorder. Along the way, they discuss such concepts as force chains, arching effects, wet grains, sticky contacts, and inertial effects. Drawing on recent numerical simulations as well as classical concepts developed in physics and mechanics, the book offers an accessible introduction to a rapidly developing field.

Book excerpt: The mechanical properties of cohesionless granular materials are evaluated from grain-scale simulations. A three-dimensional pack of spherical grains is loaded by incremental displacements of its boundaries. The deformation is described as a sequence of equilibrium configurations. Each configuration is characterized by a minimum of the total potential energy. This minimum is computed using a modification of the conjugate gradient algorithm. Our simulations capture the nonlinear, path-dependent behavior of granular materials observed in experiments. Micromechanical analysis provides valuable insight into phenomena such as hysteresis, strain hardening and stress-induced anisotropy. Estimates of the effective bulk modulus, obtained with no adjustment of material parameters, are in agreement with published experimental data. The model is applied to evaluate the effects of hydrate dissociation in marine sediments. Weakening of the sediment is quantified as a reduction in the effective elastic moduli.

Available in PDF, EPUB and Kindle. Book excerpt: This volume presents basic notions and fundamental properties of granular materials covering a wide spectrum of granular material mechanics. The granular materials may behave as fluids or solids or both. The grain size may span from microscopic to macroscopic scale. From the wet sand effect, Reynolds inspired in 1885 the notion of granular universe introducing the term "dilatancy." Bak, Tan, and Wisenfeld (1987, 1988) used the sand pile as a representative model of complex systems. In this collection of chapters, granular dynamics, granular flow from dilute to jammed states, dynamics of granular gas in microgravity, particle jetting induced by impulsive loadings, particle migration phenomena in embankment dams, and the grading entropy-based criteria of granular materials and filters are presented.

Available in PDF, EPUB and Kindle. Book excerpt: Studies in Applied Mechanics, Volume 7: Mechanics of Granular Materials: New Models and Constitutive Relations provides information pertinent to the fundamental aspects of the mechanics of granular materials. This book presents the theoretical and experimental studies of quasi-static deformations of granular materials. Organized into 30 chapters, this volume begins with an overview of the results on the description of a macroscopic stress measure and measures of the fabric of granular masses that support external loads through frictional contact. This text then introduces some quantities for the macroscopic description of mechanical and graphical characteristics of granular materials. Other chapters consider particle rolling, which appears to be a major microscopic deformation mechanism when interparticle friction is large. This book discusses as well the stress-induced anisotropy of granular materials that have initially strong anisotropic fabric. The final chapter deals with the interpretation of linear instabilities of voidage disturbances in fluidized beds. This book is a valuable resource for scientists, theoreticians, and experimentalists.
