Continuum Modeling of Granular Assemblies

Abstract

A review is given of a general method for continuum modeling of granular media. A brief discussion is given of granular contact topology and “fabric” and their relevance to various mean-field theories for mechanics and transport properties. It is show how some of the ideas can be applied to the estimation of quasi-static dilatancy and yield of frictional sphere assemblies. The appendices present a discussion of the microstructural origins of Cauchy and multipolar stresses.
