Table of Contents

Abbreviated. New formulation of graph-theoretical approach in the mechanics of granular materials (M. Satake). Derivation of constitutive law for granular materials based on dissipation functions (Y. Kishino). Micromechanics of flow and failure modes of particulate media over a wide range of strain rates (S. Nemat-Nasser, B. Balendran). Contact force distribution in granular media (F. Sidoroff et al.). Mean-field stress-strain relations for random arrays of identical spheres in tri-axial compression (J.T. Jenkins, O.D.L. Strack). Anisotropic elastic constants of granular assembly from wave velocity measurements (T.K. Agarwal, I. Ishibashi). A note on the microstructural dependence of the anisotropic elastic constants of textured materials (S.C. Cowin). Random fields and processes in mechanics of granular materials (M. Ostoja-Starzewski). A constitutive model for granular materials based on micromechanics (M.M. Mehrabadi et al.). Particle simulations of the flow of smooth spheres between bumpy boundaries (H. Kim, A.D. Rosato). The relaxation of the second moments in rapid shear flows of smooth disks (M.Y. Louge et al.). Boundary conditions for granular flows at randomly fluctuating bumpy boundaries (M.W. Richman). Experiments on ice-sphere flows along an inclined chute (K. Nishimura et al.). Simulations of rapid bimodal granular flows (M. Nakagawa, T. Imaizumi). Experimental measurements of particle diffusion and velocity profiles in a granular-flow mixing layer (M.L. Hunt, S.S. Hsiau). Some aspects of bounded and unbounded shear flows of granular material (S.B. Savage, R. Dai). Development of constitutive equations for granular materials with induced anisotropy during compaction process (S. Shima, M.A.E. Saleh). A micromechanical study of penetration tests in granular material (A.B. Huang et al.). Modified double slip model with fabric anisotropy for hardening behaviour of granular materials (Y. Tobita). An elasto-viscoplastic constitutive model for clay ba

Description

The 45 papers presented in this volume all share the common goal of constructing continuum models based on the micro behaviours of granular materials. Computer simulations continue to provide observations to aid modelling, while new experimental works begin to show promise for increased understanding in this area. Theoretical studies have extended into transitions between the rapid and quasi-static regimes and the fluid and solid mixture flows. Exciting new topics discussed in this volume include: concepts of a measure for randomness in quasi-static granular materials, which is analogous to the granular temperature in a rapid flow; scaling effects in granular media and their implications in both physical and computer simulations; instability; and boundary effects on heterogeneous behavior in simple flow configurations, which are posing new challenges for mathematical modelling. The volume will prove indispensable reading for researchers interested in the current developments in the fundamental aspects of mechanics of granular materials.
