#International Une délégation d’étudiants de l’UESTC (Chengdu) est à l’UM du 2 au 7 février pour une Winter School en mathématiques et ingénierie organisée par la @FacsciencesUM. L’événement, inauguré par @f_r_pierrot, souligne la vitalité des liens entre nos 2 universités
Excited to share that our work has just been published in two companion papers in PRL & PRE! 🎉
We provide the first experimental proof of the stress–force–fabric relation, connecting particle-scale anisotropies in sheared granular materials to bulk properties (stress & friction)
The project started at the @lorentzcenter “Getting into Shape” workshop, showing how discussions spark ideas → experiments → results

C’est un plaisir immense de remettre ce soir le diplôme de doctorat à 230 jeunes docteurs parmi le plus de 520 diplômés de la promotion 2024 du collège doctoral de l’@umontpellier @AgroParisTech @IMTMinesAles @InstitutAgroMtp ! Bravo à nos ambassadeurs !
Just out: the final piece of @SantiagoPolana's PhD 👇
We show that polydisperse granular flows collapse onto monodisperse behavior — if you pick the right length scale: the average branch length (between contacting grains). Simple. Geometrical. Unifying.

Fabulous collaboration with @NEstradaMejia (@inguniandes) @c_abrer_a and Mathieu Renouf @umontpellier @LmgcMontpellier

Dear friends: Let us share with you our recently published article "Experimental exploration of geometric cohesion and solid fraction in
columns of highly non-convex Platonic polypods" :) (link.springer.com/article/10…).

🚀 New research alert! Experimental exploration of geometric cohesion and solid fraction in columns of highly non-convex Platonic polypods 🧩
link.springer.com/article/10…
We dive into how Platonic polypods—particles with arms extruded from Platonic solids—can achieve solid-like behavior (geometric cohesion) even without adhesive forces.
The results challenge traditional granular material models, showing that certain geometries can maintain stability even in loose states.

😎Excited to share our latest research in Phys. Rev. E! Our paper explores how grain angularity affects cohesion in granular packings.
journals.aps.org/pre/abstrac…
We show that macroscopic cohesion increases with angularity and extend the “Rumpf-like” equation to include microscopic factors like contact anisotropy, grain shape, and packing structure.
Thrilled to share our latest research in Phys. Rev. Research! 🚀We present a theoretical model for steady granular flow in a rotating drum, capturing the effects of grain shape (spherical to highly concave).🎉 Bravo to my PhD student Weiyi Wang: link.aps.org/doi/10.1103/Phy…
New study! 🌟 We found a universal way to define REV in granular triaxial tests. It's not just about sample size ; it’s about force-carrying particles regardless of grading!

Next week I'll be at Polytechnique Montréal to present work in progress on the Mechanics & Physics of Granular Asteroids. This is a new research topic that I recently started with colleagues in Colorado (Paul Sánchez).
