This research develops constitutive relations and carries out a                 parametric study of internal forces generated in bulk material storage          in large silos.  A three-dimensional nonlinear finite element                   discretization analysis will be made with proper material                       characterization for loading and for unloading and material failure             criteria and with a realistic representation of interface interaction           (slip-stick) between the stored bulk material and silo wall.                    Verification of the analysis algorithm will be accomplished by                  comparing data obtained from analyzing pressure developed during                symmetric and asymmetric flow initiation in the model silo, and from            tests performed by varying the hopper angle, hopper configuration,              discharge opening width, wall friction, bulk material constitutive              relations, and segregation effects.
