The 11th edition of the GéoMécanique newsletter is brought to you by Chao Yuan. It contains the latest news regarding research publications, conference visits and other activities of the staff and students from the GéoMécanique group of Laboratoire 3SR (Sols, Solides, Structures – Risques). If you have something you want to share, please don’t hesitate to contact us at: geomecanique.newsletter@3sr-grenoble.fr. Please feel free to forward the letter to colleagues and friends, and let them know that they can subscribe by themselves here. Enjoy.
Honors, Awards and Invitations
Cino Viggiani and co-authors Carlos Santamarina, Edward Andò and Daiki Takano won the ASTM Hogentogler Award 2016 for the paper “Laboratory X-Ray Tomography: A Valuable Experimental Tool for Revealing Processes in Soils”

The paper “Population balance in confined comminution using a physically based probabilistic approach for polydisperse granular materials“, by C. OVALLE, C. VOIVRET, C. DANO HICHER P-Y. has been accepted for publication in the International Journal of Numerical and Analytical Methods in Geomechanics.
The paper “Modeling mechanical behavior of very coarse granular materials“, by Z-Y. YIN, P-Y. HICHER, C. DANO & Y. JIN, has been accepted for publication in the Journal of Engineering Mechanics.
The paper “Homogenization of a cracked saturated porous medium: Theoretical aspects and numerical implementation“, by A. Argilaga, E. Papachristos, D. Caillerie , S. Dal Pont, has been published in the International Journal of Solids and Structures.
Research projects
Félix Darve, Jacques Desrues and Luc Sibille attended the workshop of the GDRI GeoMech (International Research Group on “Multi-Physics and multi-scale coupling in Geo-Environmental Mechanics”) in La Rochelle (France) from 20 to 22 June. Jacques Desrues gave a talk about the last advances about the FEM-DEM multi-scale modelling in geomechanics.
Visits and conferences
Prof. Majid Hassanizadeh and MSc. Thomas Sweijen (hydrology group, Utrecht Univ.) visited us for three days in July, continuing our cooperation on numerical models of multiphase granular materials.
Cino Viggiani and Edward Andò attended the 17th International Conference on Experimental Mechanics in Rhodes, respectively chairing the “Rock and Soil Mechanics” session and presenting “EXPERIMENTAL MEASUREMENT OF GRANULAR FABRIC AND ITS EVOLUTION UNDER SHEARING” by Andò E., Salvatore E., Wiebicke M., Charrier P., and Viggiani G.”
People
Caroline Chalak has defended on July 1, 2016. Her PhD entitled “Multi-phase and Multi-material Interactions in Granular Media”, supervised by Felix Darve and Bruno Chareyre. The external jury members were Bernard Cambou (Ecole centrale de Lyon), Olivier Millet (Université de la Rochelle), Jean-Yves Delenne (Université de Montpellier 2), Patrick Selvadurai (McGill University), and Ehsan Nikooee (Utrecht University).
Chao Yuan has defended on July 4, 2016. His PhD entitled “Pore-scale modeling and hydromechanics of partially saturated granular materials”, supervised by Felix Darve and Bruno Chareyre. The external jury members were Pierre-Yves Hicher (Ecole Centrale de Nantes), S. Majid Hassanizadeh (Utrecht University), Antonio Gens (Universitat Politècnica de Catalunya), and Jean-Michel Pereira (Ecole des Ponts ParisTech).
Luc Sibille has defended his “Habilitation à Diriger des Recherches (HDR)”, entitled “Internal erosion and failure in grainy soils” on Wednesday 6th July in Grenoble. The external jury members were Eduardo Alonso (Universitat Politècnica de Catalunya), Guillaume Chambon (IRSTEA), Farhang Radjaï (CNRS), Christian Geindreau (Université Grenoble Alpes), Didier Marot (Université de Nantes), and François Nicot (IRSTEA). HDR is a French degree (beyond the PhD degree) giving access to the supervision of PhD students and to the application to Professor positions.
