The behavior of the granular bulk material is based on a consistent continuum mechanics approach formulated in an ALE (Arbitrary Lagrangian Eulerian) frame of reference, allowing to describe the behavior of the material from static conditions up to steady state flowing conditions. As the flowing material is of main interest, the numerical model takes into account a dynamic equilibrium condition including inertia effects, large strains and large displacements. The behavior of the ensiled material is simulated by a non linear elastic constitutive law associated with the plastic model of Drucker Prager. A comparative analysis of stress fields within the granular bulk material as well as the resulting wall pressures is performed during the discharge of a full scale experimental silo for two different materials stored.
