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)
