| Outline of Final Research Achievements |
We have developed hybrid simulation techniques for granular materials that can account for both macroscopic and microscopic physical processes, by coupling discrete element method and continuum modeling. Our methods use discrete elements only for free surfaces and regions where the so-called size effects (due to the grains having finite sizes) are significant, and use continuum elements for regions that are homogenizable. Using our methods, we can handle size effects that could not be handled using only continuum elements, e.g., grains can jam at a small orifice and may form shear bands with a finite thickness, while much reducing the computation cost.
