Abstract
A finite element analysis is presented to calculate the steady-state v elocity fields in a cohesionless granular solid discharging from a pla nar Aat-bottomed silo. The work expands and generalises the Tuzun and Nedderman (1979) theory to treat a wide range of geometries, material properties and boundary conditions. The approach is kinematic and grav ity-based, solving for the velocity field and assuming complete stress independence. Copyright (C) 1996 Published by Elsevier Science Ltd
