The 5th edition of the GéoMécanique newsletter is brought to you by Chao Yuan. It contains the latest news regarding research publications, conference visits and other activities of the staff and students from the GéoMécanique group of Laboratoire 3SR (Sols, Solides, Structures – Risques). If you have something you want to share, please don’t hesitate to contact us at: geomecanique.newsletter@3sr-grenoble.fr. Please feel free to forward the letter to colleagues and friends, and let them know that they can subscribe by themselves here. Enjoy.
Publications
The paper “Relation between microstructure and loading applied by a granular flow to a rigid wall using DEM modeling”, by Adel Albaba, Stéphane Lambert(*), François Nicot(*) and Bruno Chareyre, appeared in Granular Matter (full paper). (*IRSTEA)
The paper entitled “Modeling of fluid leakage through multi-cracked RC structural elements using a numerical probabilistic cracking approach”, by G.Rastiello, C.Desmettre, J.Tailha, P.Rossi, J.Charron and S.Dal Pont, has been accepted for publication in Materials and Structures.
An extension of the DEM method implemented in Yade-DEM is described in “Modelling of deformable structures in the general framework of the discrete element method”, recently published in Geotextiles & Geomembranes by Anna Effeindzourou*, Bruno Chareyre, Klaus Thoeni*, Anna Giacomini*, and François Kneib. It results from a collaboration with our colleagues from Newcastle AU. （*Univ. Newcastle， Australia)
