Zeynep successfully defended her PhD at the University of Edinburgh on the 4th of September with Florian Fusseis and Matthew Coop as assessors. The title of her thesis is “A study of temporal and spatial evolution of deformation and breakage of dry granular materials using x-ray computed tomography and the discrete element method” and it will be available online by the end of December. Well done Zeynep!
Alice Di Donna is the latest addition to our team. She has obtained a position of “Maitre de Conférences” (Assistant Professor) at Université Grenoble Alpes, effective since September 1st 2017. Alice obtained a Masters degree at UJF Grenoble and Politecnico di Torino back in 2009, then a PhD at EPFL, Switzerland, in 2014. After that, she performed a postdoc at the Politecnico di Torino and worked at the same time as a professional engineer at Teknema Progetti srl in Torino. Welcome Alice!
Floriana Anselmucci will soon start her PhD entitled “Roots-soil interactions: effects on soil micro-structure” under the supervision of Luc Sibille and Chloé Arson in Georgia Tech.
Related to the above, Evelyne Kolb (UPMC Paris) and Lionel Dupuy (University of Dundee) visited 3SR on the 25th of September to discuss about roots in soil.
Sabatino Cuomo (University of Salerno, Italy) is at 3SR since September 18. He will be with us until mid October — with funding from Labex Tec21 for visiting professors.
Jelke Dijkstra will visit 3SR 26-29th of September to discuss with Christophe Dano, Imane Salama and Eddy Andò about Imane’s ongoing PhD work, the current ESRF synchrotron experimental campaign and the next one too.
The paper “Numerical modeling of high aspect ratio flexible fibers in inertial flows” by D. Kunhappan, B. Harthong, B. Chareyre, G. Balarac, and P. J. J. Dumont has been accepted for publication in Physics of Fluids.
Max Wiebicke, Edward Andò, Ivo Herle, And Cino Viggiani’s paper “On the metrology of interparticle contacts in sand from x-ray tomography images” was accepted for publication in Measurement Science and Technology’s Special Issue entitled “Advanced X-Ray Tomography”.
Zeynep Karatza, Edward Andò, Stefanos-Aldo Papanicolopulos, Jin Y. Ooi and Cino Viggiani’s paper “Evolution of deformation and breakage in sand studied using x-ray tomography” was accepted for publication in Géotechnique.
Ilaria Soriano, Erdin Ibraim (University of Bristol), Edward Andò, Andrea Diambra (University of Bristol), Tanguy Laurencin, Paolo Moro and Cino Viggiani’s paper “3D fibre architecture of fibre-reinforced sand” was accepted for publication in Granular Matter.
Visits and conferences
Jacques Desrues and Pierre Bésuelle participated to the Clay Conference 2017 in Davos, Switzerland, from 24 to 27 September, to present both a work on a Callovo-Oxfordian clay rock multiscale experimental caracterisation of the deformation and material anisotropy, and also a double scale modeling by numerical homogeneisation (FEM2) of the clay rock using the enriched (more realistic) miscrostructure elaborated by Benoit Pardoen (post-doc in 3SR).
Orianne Jenck, Abdel Ali Dadda, Fabrice Emeriault and Cino Viggiani attended the 19th ICSMGE in Seoul, South Korea.
- Orianne Jenck presented a paper co-authored with D. Ricotier, D. Dias and L. Oxarango on “Multidisciplinary project-based learning for geotechnical and civil engineering students, to acquire fundamental concepts “, during a session organized by the TC306 on Geo-Education.
- Fabrice Emeriault presented a paper co-authored with O. Jenck and M. Houda on “Numerical back analysis of the behaviour of soft soil improved by rigid piles under cyclic loading” during a session organized by the TC211 “Ground improvement”.
- Cino gave an invited talk at the workshop organized by TC105 “Geomechanics from Micro to Macro” and was a invited panel member at the workshop “What should graduates be able to do and What and How to teach to”, organized by TC306 “Geo-Education”
Pierre Bésuelle, Edward Andò, and newcomers Nicolas Lenoir and Alice DiDonna went to the French national radioactive waste management agency’s (ANDRA) headquarters in Châtenay-Malabry (near Paris) for a meeting on the role of full-field imaging for mechanical testing on the Caollovo-Oxfordian clay-rock.
Alice Di Donna attended the 6th meeting of the Cost Action GABI-Geothermal Applications for Buildings and Infrastructure, which took place in Sofia, Bulgaria.
