This introductory review of dense-phase powder flows consists of two parts. The first, concerned with the precedents in continuous or dense solids, discusses three topics: plastic flow, fracture, and solid-solid friction. The second part follows this scheme for particle systems, drawing on the descriptions provided for continua. The intention is to provide a general introduction to these topics for those readers who have only a limited familiarity with this subject, which is now attracting a growing interest as reflected, for example, at the winter school on the physics of granular media, held at Les Houches Physics Centre, France (Bideau and Dodds, 1991). |
