“…From a constitutive point of view, the silo analyses used hitherto the following models: elasto-plastic [1], [2], hypoplastic [2], polar elasto-plastic [1], [3][4][5][6], polar hypoplastic [5], [7], visco-plastic [8], [9], viscoelastic-plastic [10][11][12][13], visco-hypoplastic [14] and own ones [15], [16]. The models used were established in Lagrangian coordinates [1], [3][4][5], [7], [13], in Eulerian coordinates [8][9][10][11][12], [14] and in Lagrangian-Eulerian coordinates [2], [6] according to the particle-in-cell scheme [17]. The FE-calculations carried out in [5] have shown that the analyses performed in a Lagrangian format are able to consider only the onset of the silo flow due to a large mesh distortion at the outlet.…”

This paper contains results of numerical modelling of the onset of silo flow for granular material in a model silo with convergent walls. The calculations were performed with a finite element method based on a polar elasto-plastic constitutive relation by Mühlhaus. It differs from the conventional theory of plasticity by the presence of Cosserat rotations and couple stresses using a mean grain diameter as a characteristic length. The characteristic length causes that numerical results do not depend upon the mesh discretisation. The model tests on rapid silo flow of glass beads performed by Renner in a glass hopper with a large wall inclination from the bottom were numerically simulated. The FE-calculations were performed for plane strain by taking into account inertial forces and linear viscous damping. A satisfactory agreement between numerical and experimental results was obtained. In addition, the FE-calculations were performed for very rough walls. Advantages and limitations of a continuum approach for simulations of rapid silo flow were outlined.

“…FEM associated with elastoplastic constitutive theories can give satisfactory predictions of the internal stress and wall pressure in hoppers (Ooi and Rotter, 1990;Rotter et al, 1998;Goodey et al, 2003Goodey et al, , 2006Goodey and Brown, 2004;Vidal et al, 2006Vidal et al, , 2008Ding et al, 2013). However, its application to reproduce the flow conditions of granular material is usually not easy Sanad et al, 2001;Tejchman and Klisiński, 2001) and requires some particular schemes or treatments such as the re-meshing and re-zoning scheme (Sanad et al, 2001), adaptive meshing technique (Yang et al, 2011), viscoplastic granular fluid models (Haussler and Eibl, 1984;Karlsson et al, 1998;Elaskar et al, 2000;Böhrnsen et al, 2004), smoothed particle hydrodynamics (SPH) method (Sugino and Yuu, 2002), and material point method (MPM) (Wieckowski et al, 1999).…”

“…However, because of excessive moisture content in the extracted ingots, the refinery questioned the quality of ingot flow in the silo. Modelling (Karlsson et al, 1998;Hirshfeld and Rapaport, 2001;Yang and Hsiau, 2001;Goda and Ebert, 2005) and laboratory tests (Yang and Hsiau, 2001;Medina et al, 1998;Ostendorf and Schwedes, 2005;Degouet et al, 2007b) can be used to describe silo flow-patterns. Unfortunately, extrapolation of these observations to full-scale industrial silos is most uncertain and requires experimental data.…”
