This research is concerned with an interdisciplinary team                  studying multidimensional, time dependent problems arising from                 plastic deformation of materials, especially granular materials                 and porous metals.  The goals of the project are to develop a                   detailed numerical simulation of the flow of granular material                  in an industrial or agricultural silo and of the flow of metal                  in a forming process and to verify the numerical predications                   by appropriate experiments.                                                          Technologically, progress on these problems should lead to                 safer and more reliable industrial silos and to greater                         efficiency in metal forming processes.  Scientifically, these                   problems involve several interesting mathematical issues;                       ill-posed partial differential equations, homogenization of                     media with microstructure, and large scientific computations.
