The 10th 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.
Publications
Cino Viggiani and Edward Andò co-authored a paper in JMPS with Reid Kawamoto and José Andrade in Caltech: Level set discrete element method for three-dimensional computations with triaxial case study.
The paper “Partially saturated media: from DEM simulation to thermodynamic interpretation” has been accepted for publication in the European Journal of Environmental and Civil Engineering, by the authors Caroline Chalak, Bruno Chareyre, Ehsan Nikooee, and Félix Darve.
“The Effects of Swelling and Porosity Change on Capillarity: DEM Coupled with a Pore-Unit Assembly Method” by T. Sweijen, E. Nikooee, S.M. Hassanizadeh and B. Chareyre has been published in Transport in Porous Media 113 (1), 207-226.
“DEM Analysis of Geomechanical Properties of Cemented Methane Hydrate–Bearing Soils at Different Temperatures and Pressures“, by M. Jiang, J. He, J. Wang, B. Chareyre and F. Zhu, has been published by International Journal of Geomechanics, 16(3), 04015087.
Research projects
A post-doc scholarship as been granted by labex Tec21 to the project “PFV embedding LBM: a new numerical tool for micro-hydro-mechanical couplings”, supervised by B. Chareyre in collaboration with Majid Hassanizadeh (Utrecht Univ.) and Antonio Gens (UP Catalunya).
Visits and conferences
The fourth Workshop on Modern Trends in Geomechanics (IW-MTiG4) took place in Assisi (Italy) from April 16 to April 18. Its format followed the established workshop tradition in which presentations are given by invited leading experts in various fields of geomechanics, including constitutive modeling, experimental geomechanics, analytical and numerical methods, micromechanics, coupled multiphysics processes and engineering applications. 33 speakers were invited to present at the workshop. With over 100 participants, including many PhD students, this workshop was a true success!
Participants from 3SR: Jacques Desrues and Bruno Chareyre (both invited speakers), Jeanne Doreau Malioche, Rodaina Aboul Hosn, Thanos Papazoglou, Edward Andò, Alessandro Tengattini, Ilaria Soriano, Max Wiebicke and Cino Viggiani (who was one of the organizers of the workshop).

The 29th and 30th of April, some of the main the participants of the European SOMEF project (Soil Mechanics Fabric) met in Grenoble to share recent results. We heard about the developments on the Athens side of the 3D scan line approach for measuring void anisotropy, visited the lab and our recently acquired loading systems, presented our experimental results in triaxial extension, our metrological work on contact detection and orientation and learned about the work of the Montpellier group on the numerical particle-scale modelling of clays and their anisotropy.
