Grenoble Geomechanics Newsletter No. 36

Et le voila! As the end of spring gives way to a lively world filled with open bars, sunny parks, and green mountains – the Grenoble GéoMécanique group continues producing new projects, new publications, new talks, and new personnel! Read our 36th Grenoble Geomechanics Group Newsletter for details!



New projects:

  • Dominique Daudon will study DEM modeling of Pircas embankment stones (Incas technology) under seismic loading during her new ECOS mobility project which has a duration of  3 years. The project “Sarra” is coordinated by Frederique Leblanc, of Laboratoire Jean Kuntzman (LJK), to study “small rockfall run out” and it is funded by UGA. The collboration implies LJK, Laboratoire 3sr, the University of Bordeaux (Vincent Couallier) and Irstea (Franck Bourrier)

A look at some recent publications:

  • Amato, G., Andò, E., Lyu, C. et al. (2021) A glimpse into rapid freezing processes in clay with x-ray tomography. Acta Geotech.
    This fascinating article was carried out in 2019 by our former M.Sc student, Giorgia Amato, under the main supervision of Gudmund Reinar Eiksund, who was on sabbatical at 3sr during the research.
  • Edward AndòBenjy Marks and Stéphane Roux  (2021) Single-projection reconstruction technique for positioning monodisperse spheres in 3D with a divergent x-ray beam
  • Luc Sibille, Nadia Benahmed, Félix Darve (2021). Constitutive response predictions of both dense and loose soils with a discrete element model, Computers and Geotechnics, Volume 135,
  • Anna Herring, Penelope L. King, Mohammad Saadatfar, Fatin Mahdini, Afiq Muzhafar Kemis Yahyah, Edward Andò, (2021) 3D microstructure controls on mineral carbonation. Journal of CO2 Utilization.

In other news:

  • Øyvind Torgersrud has taken a break from his job at the NGI (Norwegian Geotechnical Institute) to start a PhD with Eddy and Cino, to be co-supervised by Jose Andrade at Caltech (USA) and Hans Petter Jostad in NGI. He will study granular mechanics both with x-ray tomography and LS-DEM. We can expect him to be working in Grenoble for all of 2022 and possibly longer.
  • Eddy (Edward Andò) has temporarily left the 3SR and is now a visiting professor in Katrin Beyer’s lab in EPFL.
  • Gustavo Pinzon and Cyrille Couture both presented their work at “IROAST short virtual event”, covering their experimental campaigns focused on imaging porous media. The meeting was hosted by the University of Kumamoto on May 12, 2021.
  • Cino gave a spirited keynote lecture at the (virtual) german soil mechanics conference (Bodenmechanik-Tagung) on April 21, 2021 where he discussed recent developments in x-ray and neutron imaging for geomechanics.
  • Cyrille Couture started a 6-month post-doc at the ILL working with Alessandro to study the hydromechanics of multiphase fluid fingering in granular material.
