Modeling and computational issues in slow granular flows

Abstract: In this talk, various mathematical approaches for the study of granular flows will be reviewed. Specific plasticity models will be illustrated on two examples of practical relevance: pile formation and hopper flows. These types of applications lead to a wide range of mathematical problems, such as Hamilton-Jacobi, free boundary problems, and elliptic and hyperbolic systems of partial differential equations. Open mathematical and modeling problems will be identified. Several computational issues will be discussed along with computational and experimental results.
