Dynamics and Control of Mechanical Energy Propagation in Granular Systems
Abstract
The STIR project focused on a set of highly challenging problems to set the stage for future work at a deeper level. These problems are (1) to design a circuit system that simulates the transformation of an incident impulse into a solitary wave, (2) to study how the width of a solitary wave depends on the geometry of the grain-grain contacts, (3) how to make solitary waves in noisy environments, (4) to find what kind of physical situations precipitate large energy fluctuations in nonlinear systems and (5) how to model the presence of fluids in the inter-stitial space between grains in a 3D granular bed. All of these tasks have either been accomplished or have seen substantial progress during the period of this exploratory study. The report details the findings.
