DEM Simulations of Bonded Granular Materials

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 can be 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 at a graduate level who are majoring in civil engineering, materials 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.
