ABSTRACT: Granular systems are ubiquitous in our experience, and they control the physics of many natural phenomena that are societally relevant such as slope failures (e.g., landslides and man-made embankments) and earthquakes. Furthermore, grain transportation, pouring, packing, and flowing are essential processes in fields such as food, pharmaceutical, and construction material industries. Thus, developing tools for understanding the dynamics of granular flow, at different strain rates, pressures, and temperatures is crucial for optimization of resources in industry and for development of improved hazard models for our built environments. In this talk, Elbanna reports on his recent progress in computational modeling of granular dynamics with a special focus on applications related to multiscale earthquake physics.
