WebIncipient Flow in Silo‐Hopper Configurations. A finite element model to analyze the case of incipient flow for cohesionless material in silos is presented. The model is formulated on … WebDeep, filled silos with high stress eccentricity and large wall normal angles are not viable. Incipient flow and the stress switch have been simulated. Output data suggest wide variation in wall stresses both axially and azimuthally are possible, at high stress eccentricities, which would have structural implications.
