Advances in Multi-Physics and Multi-Scale Couplings in Geo-Environmental Mechanics reunites some of the most recent work from the French research group MeGe GDR (National Research Group on Multiscale and Multiphysics Couplings in Geo-Environmental Mechanics) on the theme of multi-scale and multi-physics modeling of geomaterials, with a special focus on micromechanical aspects.

Its offers readers a glimpse into the current state of scientific knowledge in the field, together with the most up-to-date tools and methods of analysis available.

Each chapter represents a study with a different viewpoint, alternating between phenomenological/micro-mechanically enriched and purely micromechanical approaches. Throughout the book, contributing authors will highlight advances in geomaterials modeling, while also pointing out practical implications for engineers.

Topics discussed include multi-scale modeling of cohesive-less geomaterials, including multi-physical processes, but also the effects of particle breakage, large deformations on the response of the material at the specimen scale and concrete materials, together with clays as cohesive geomaterials.

The book concludes by looking at some engineering problems involving larger scales.

1. Multi-Scale and Multi-Physics Modeling of the Contact Interface Using DEM and Coupled DEM-FEM Approach, Mohamed Guessasma, Valery Bourny, Hamza Haddad, Charles Machado, Eddy Chevallier, Aymen Tekaya, Willy Leclerc, Robert Bouzerar, Khaled Bourbatache, Christine Pélegris, Emmanuel Bellenger and Jérôme Fortin. 2. Adsorption-induced Instantaneous Deformation in Double Porosity Media: Modeling and Experimental Validations, Laurent Perrier, Frédéric Plantier, Gilles Pijaudier-Cabot and David Gregoire. 3. Granular Materials: Mesoscale Structures and Modeling, Zhu Huaxiang, Hélène Magoariec, Eric Vincens, François Nicot, Bernard Cambou and Félix Darve. 4. Behavior of Granular Materials Affected by Grain Breakage, Christophe Dano, Carlos Ovalle, Zhen-Yu Yin, Ali Daouadji and Pierre-Yves Hicher. 5. Multi-scale Modeling of the Mechanical Behaviour of Clays, Zhen-Yu Yin and Pierre-Yves Hicher. 6. Modeling of Complex Microcracking in Quasi-Brittle Materials: Numerical Methods and Experimental Validations, Thanh Tung Nguyen, Julien Yvonnet, Michel Bornert and Camille Chateau. 7. Multi-Scale Methods for the Analysis of Creep-Damage Coupling in Concrete, Mounia Farah, Jacqueline Saliba, Frédéric Grondin and Ahmed Loukili. 8. Effect of Variability of Porous Media Properties on Drying Kinetics: Application to Cement-based Materials, Nabil Issaadi, Abdelkarim Aït-Mokhtar, Rafik Belarbi and Ameur Hamami. 9. State of the Art on the Likelihood of Internal Erosion of Dams and Levees by Means of Testing, Pierre-Yves Hicher, Didier Marot and Luc Sibille. 10.
