DEM Simulations of Bonded Granular Materials is intended to introduce the advancement of the distinct element method (DEM) and its particular application to typical bonded geomaterials including cemented sands, unsaturated sands, lunar regolith and methane hydrate bearing sands. After introducing contact models for different bonded geomaterials, the merit of DEM to cemented geomaterials is demonstrated through simulations of laboratory tests and engineering applications which are problematic using conventional continuum-based approaches. This book is of value to those who are interested in the mechanical behavior and numerical simulations of natural particulate systems of complexity. It can be used as a textbook or reference for students of graduate level majoring civil engineering, material science and relevant subjects. This book systematically introduces the basic principle and application of DEM to bonded materials based on the first-hand research experiences gained by the author and his research team. A systematic introduction on the fundamental principle of DEM analysis on bonded granular materials and a thorough review of the advancement of DEM simulations.Features the state of art of bond contact models proposed for atypical bonded geomaterials such as cemented sands, methane hydrate bearing sands, lunar regolith, rocks and unsaturated loess.Presents engineering application of DEM simulations associated with bonded geomaterials, such as submarine landslides triggered by dissociated methane hydrate, wheel-soil interaction on the moon, rock slide due to weathering, pile capacity in seabed with methane hydrate. INDICE: 1. Introduction 2. A conceptual framework of the contact model for bonded geomaterials 3. Contact behavior of bonded particles: micro mechanical experiments 4. The bond contact models for atypical bonded geomaterials 5. Engineering applications
