    • A general method for modelling deformable structures in DEM 

      Effeindzourou, A.; Thoeni, K.; Chareyre, B.; Giacomini, A. (CIMNE, 2015)
      Conference report
      Open Access
      The discrete element method was originally designed to handle rigid spherical particles. In this work, the method is extended to model arbitrary deformable structures, such as membrane and container structures. The paper ...

    • A hybrid multiphase model based on Lattice Boltzmann method direct simulation 

      Montellà, E.P.; Yuan, C.; Chareyre, B.; Gens Solé, Antonio (CIMNE, 2019)
      Conference report
      Open Access
      By means of the multicomponent Shan-Chen lattice Boltzmann method (LBM), we investigate the multiphase flow through porous media. Despite the excellent accuracy of the LBM, large domains result in unaffordable computational ...

    • A pore-scale approach of two-phase flow in granular porous media 

      Yuan, C.; Chareyre, B.; Darve, F. (CIMNE, 2015)
      Conference report
      Open Access
      A pore-scale model is presented for simulating two-phase flow in granular materials. The solid phase is idealized as dense random packings of polydisperse spheres, generated with the discrete element method (DEM). The pore ...

    • A pore-scale hydro-mechanical coupled model for geomaterials 

      Catalano, E.; Chareyre, B.; Cortis, A.; Barthelemy, E. (CIMNE, 2011)
      Conference report
      Open Access
      We present a model for fluid-saturated granular media coupled flow and mechanical deformation. The fluid is assumed to be incompressible and the solid part is assumed to be a cohesive granular material. Forces exerted by the ...

    • Investigation of internal erosion processes using a coupled DEM-fluid method 

      Sari, H.; Chareyre, B.; Catalano, E.; Philippe, P.; Vincens, E. (CIMNE, 2011)
      Conference report
      Open Access
      The evolution of granular beds subjected to upward seepage flow is investigated using a coupled DEM-fluid model implemented by Catalano et al. in the open-source software Yade-DEM. Firstly, filtration properties of a coarse ...

    • Numerical simulations of dense suspensions rheology using a dem-fluid coupled model 

      Marzougui, D.; Chareyre, B.; Chauchat, J. (CIMNE, 2013)
      Conference report
      Open Access
      The understanding of dense suspensions rheology is of great practical interest for both industrial and geophysical applications and has led to a large amount of publications over the past decades. This problem is especially ...

    • What is wrong in love-weber stress for unsaturated granular materials? 

      Chalak, C.; Chareyre, B.; Darve, F. (CIMNE, 2015)
      Conference report
      Open Access
      This paper presents the micromechanical model for unsaturated soil in pendular regime, taking into account the roughness of the grains and the interfaces that separate the different phases present in the medium. It supplements ...
