Abstract : The objective of this study was to establish a physically realistic continuum theory for granular media. Granular materials are considered here to be a two or three phase cohesionless system that is a mixture of solid granules whose diameters are in excess of 0.002 mm, air and/or water. The real materials that may be classified as granular are numerous, e.g. soil, sand, gravel, fresh concrete, bird shot, and seed grain. The primary concern with some of these materials is their behavior in flow, transport, and storage. For others the major interest is in their behavior under applied loading and self-weight, such as in slopes, fills, and foundations. A concern of current interest is lunar soil or dust whose behavior should be estimated before planning structures and transportation systems to be used on the moon. (Author)
