Grenoble Geomechanics Newsletter No. 35

Well, well, well. You’ve decided to read the brand new Geomechanics Newsletter. Good choice :) Our 35th newsletter presents a range of happenings including the release of our beautiful new Activity Report, which contains all sorts of GéoMécanique group research. In other news, we have 11 in-house Master’s students starting their research projects next week, and as usual – an incredible amount of publications.  As always: read on for details!

Thanks to Vincent Richefeu & Antoine Mertz for their hard work organizing, collecting, and compiling the work of over 14 researchers and 25 PhD students. The report presents the hard work of Grenoble Geomechanics Group and covers a wide range of topics including, but not limited to:

  1. Multi-scale analysis of geomaterials
  2. Interfaces, soil-structure interactions and civil engineering structures
  3. Bio-chemo-mechanical interactions
  4. Thermo-hydro-mechanical coupling

Take a deep dive into our work by downloading the pdf book.

Deconfinement – for the calibration chamber

Our dear old rusty calibration chamber was removed from its underground resting position to make way for a smaller, younger, (but less distinguished) calibration chamber. In the end, 3SR will be one of the only labs in the world to have two calibration chambers of different sizes. Such an asset will enable further research into size-effect.

Thanks to Ankit, Payam, and Laurent for contributing their manual labor to the 3 tonne excavation!

Les stages commencent!

You may notice we have 11 new Master’s internships starting at the beginning of March. Their projects range from experimental work with the Tomo, to numerical work with various softwares. Among them we have:

Erika INCARDONA / Ibraheem KHAN / Georges MOUALLEM / Panteleimon


Cino has now resorted to virtual globetrotting in his recent PoreLab webinar ( His presentation covering imaging processes in relation to geomaterials laboratory testing can be viewed here.
