Particulate Discrete Element Modelling

Particulate discrete element analysis is becoming increasingly popular for research in geomechanics as well as geology, chemical engineering, powder technology, petroleum engineering and in studying the physics of granular materials. With increased computing power, practising engineers are also becoming more interested in using this technology for analysis in industrial applications. This is the first single work on DEM providing the information to get started with this powerful numerical modelling approach.

It presents a theoretical overview of DEM as well as practical guidance on running DEM simulations and interpreting DEM simulation data with a geomechanics slant.

"This book is unique in the market, not only because it is the only introductory text of DEM written with so much practical advice for users, but also because of its unique attention to the audience in the area of geomechanics. ... An excellent reference textbook for a graduate course on DEM; it is also an excellent self-study reference for an individual graduate student or engineer who plans to carry out DEM."-- Helen Cheng, Géotechnique "This volume on the theory and application of the particulate discrete element modeling approach is the first of its kind in the geomechanics community, and it represents a valuable and highly useable reference for a range of readers interested in numerical mechanical modeling." Amanda N. Hughes, Pure and Applied Geophysics "This volume on the theory and application of the particulate discrete element modeling approach is the first of its kind in the geomechanics community, and it represents a valuable and highly useable reference for a range of readers interested in numerical mechanical modeling."PAGEOPH, 2014
