After some (well) deserved holidays, our GéoMéchanique group at Laboratoire 3SR (Sols, Solides, Structures – Risques) is back on track, ready to continue with the experiments, simulations, and top-tier research! Find all the news in the 41st edition of our newsletter. Please forward this letter to colleagues and friends. Enjoy!

Journées en l’honneur de Jacques et Denis
Two half-days were organised by the laboratory in the honor of Jacques Desrues and Denis Caillerie. It took place between the 26th and 27th of January and held talks by Robert Charlier (Université de Liège, Belgium), Stéphane Andrieux (ONERA, France), Pierre Suquet (CNRS, LMA, Marseille, France), Michel Bornert (Laboratoire Navier, Paris, France), Pierre-Simon Jouk (TIMC, Grenoble, France), René Chambon (3SR, Grenoble, France), Claudio Tamagnini (Università di Perugia, Italy), and Annie Raoult (Laboratoire MAP5, Paris, France).
Claudio Tamagnini (Università di Perugia, Italy) spent one month at the lab as an invited professor — from January 15 to February 15. A friend of Cino’s and an expert in Numerical Modeling in Geomechanics, he is helping Chiara (PhD student of Cino, Alessandro and Pierre) not only with the correction of the formulation of her model for Cemented Granular Materials but also with the implementation of the latter in Finite Elements.
- On November 3rd, Yosuke Higo (from Kyoto University, Japan) gave a talk about “Morphological transitions of pore water during triaxial compression in unsaturated soil”. More information in https://3sr.univ-grenoble-alpes.fr/fr/actualites/yosuke-higo.
- Chunjing Ma defended his thesis titled “Numerical assessment of the behaviour of energy tunnels” on November 14th 2022, under the supervision of Daniel Dias and Alice Di Donna. The jury was composed of: Fleur Loveridge (Leeds University, UK), Hussein Mroueh, (Lille Sciences & Technologies, France), Fabrice Emeriault, (University of Grenoble Alpes, France), Alessandro F. Rotta Loria, (Northwestern University, US), and Iulia Prodan (Technical University of Cluj-Napoca, Romania).
- On November 22nd, our amazing Angela Casarella successfully defended her PhD work “Multi-scale investigation of the thermomechanical behaviour of non-active clay”, under the supervision of Vincent Richefeu, Alice Di Donna, and Alessandro Tarantino (Strathclyde University, UK). The jury was composed of: Gioacchino Viggiani (Université Grenoble Alpes, France), Juan Carlos Santamarina (KAUST, Saudi Arabia), Pierre Delage (École des Ponts ParisTech, France), Catherine O’Sullivan (Imperial College London, UK), and Jelke Dijkstra (Chalmers University of Technology, Sweden).
- On December 16th, Ankit Sharma defended his PhD work, funded by Equaterre group, on the “Development and experimental validation of a new in-situ geotechnical test – Cyclic CPT, with emphasis on identifying liquefiable soils”. The jury was composed of Dr. M. ARROYO ALVAREZ DE TOLEDO (reviewer, UPC Barcelona), Dr. P. REIFFSTECK (reviewer, UGE Paris), Pr. F. EMERIAULT (president, INP Grenoble), under the collective supervision of B. Chareyre (PhD director), L. Sibille and C. Dano, all from 3SR and P. Riegel and P. Sadrabadi (Equaterre).
(Future) PhD graduates
- On March 31st Ilija Vego will defend his thesis “Multi-modal investigation of hygroscopic granular media at high relative humidity” under the supervision of Cino Viggiani, Alessandro Tengattini, and Edward Andò. The jury is composed of Prof. Emilien Azéma (Université de Montpellier, France), Prof. José E. Andrade (California Institute of Technology, US), Prof. Karen E. Daniels (North Carolina State University, US), and Gaël Combe (Université Grenoble Alpes, France).
- On March 14th Gustavo Pinzón will defend his PhD titled “Experimental investigation of the effects of particle shape and friction on the mechanics of granular media”, under the supervision of Cino Viggiani, Edward Andò, and Alessandro Tengattini. The jury is composed of Prof. Farhang Radjai (Université de Montpellier, France), Prof. Jean Michel Pereira (École des Ponts ParisTech, France), Prof. Gaël Combe (Université Grenoble Alpes), Prof. Catherine O’Sullivan (Imperial College London, UK), Prof. Antonio Gens (Universitat Politècnica de Catalunya), and Prof. Stephen Hall (Lund University, Sweden).
New PhD students
In November 2022, Michela Arciero started her PhD project “Multi-scale analysis, laboratory design in seismic field and study of soil reinforcement techniques with a sustainable perspective” under the supervision of Giuseppe Modoni (University of Cassino and Southern Lazio) and Gioacchino Viggiani (UGA, 3SR Laboratoire).
Six students of the international master program in Geomechanics have started their second-semester research project and will work in our team: Coraly Corneio (from Bolivia), Georgios Felekis (from Greece), Elena Ilari (from Italy), Aoxin Li (from China), Saad Mortadi (from Morocco), and Birhan Woldemichael (from Ethiopia). We look forward to hearing from them about what are they working on — perhaps in a team meeting soon?
