Inside the Structure of Granular Materials: Chains, Cycles and Scale Effects provides an updated overview of the latest results related to the microstructural understanding of the mechanical behavior of granular materials. In particular, this book considers different scales of analysis, from the macroscopic scale (at which constitutive relations can be inferred) to the microscopic scale (namely, the particle or the contact scale). This book emphasizes the intermediate scale consisting in grain clusters (cycles or force chains).
