Résumé

Granular materials challenge researchers and engineers in various fields not only because they occur with a broad variety of grain sizes, shapes, and interactions in nature and industry, but also because they show a rich panoply of mechanical states. Despite their polymorphism, all these different types of soils, powders, granules, ores, pharmaceutical products, etc., are instances of granular matter with the same least common denominator of being sandlike (psammoid in Greek), i.e., solid grains interacting via frictional contacts. With nearly 400 research papers, this volume provides a general picture of current research on granular materials across the world. The topics covered by this volume range from small deformations of particles interacting through enduring frictional-elastic contacts to rapid flows of particles that exchange momentum and energy in multiple collisions, either in single phase or particle-fluid multi-phase flows. Applications range from powder processing to chemical engineering and modeling of geomaterials. This volume also covers four emerging sectors of research: particle shape effects (with broad scopes for designing innovative behaviors), granular suspensions (bridging between the two distinct communities of non-Brownian suspensions and immersed granular flows), particle breakage (with crucial relevance to most fields of application), material instability (implying failure mechanisms under various loading conditions), and environmental granular processes (including bio-stabilization of slopes, root-soil interactions, large-scale geological processes and astryphysics of, e.g., asteroids).
