Characterizing the Dynamics of Geo-Surface Materials: Modeling and Simulation Challenges and Opportunities
August 17-18, 2016
Courtyard Marriott Chicago Downtown/River North, 30 East Hubbard Street, Chicao, Illinois 60611
Goal of the Workshop
This workshop’s goals are to : (a) identify open problems that pertain to the dynamics of geo‐surface materials; and (b) understand whether recent fundamental advances in geophysics, applied mathematics, and computational science can combine in a multi‐disciplinary fashion to produce a breakthrough in the broad area of geo‐surface dynamics characterization. The outcome of this workshop will be a technical report identifying a set of multidisciplinary basic research thrusts that can lead to breakthroughs in our understanding of issues related to the topic of interest.
Rationale
Recent theoretical, algorithmic, and advanced computing breakthroughs are providing a fresh opportunity to revisit several open problems pertaining to the modeling and simulation of the dynamics of geo‐surface materials. Assuming a broad range of forms ‐ from dry/saturated sand to silt to clay ‐ the problem of interest brings to the fore unique modeling and simulation challenges at the interface of applied math (homogenization, handling of discontinuous behavior, discrete vs. continuum representations, fluid‐solid interaction, plasticity aspects), computer science (large scale simulation, parallel computing), and practical application (soft‐matter physics, machine‐ground interaction).
