Non-Invasive, Photochromic-Tracer Studies of Particulate Suspensions and Granular Media
This is a summary of research performed under the subject AFOSR grant on the micromechanics, continuum mechanics and transport properties of granular media and geomaterials. It has involved the development of new theoretical models of microstructure, numerical simulation of granular assemblages, and experimental observation on model systems. The overall goal of the work is to provide a sound microstructural basis for understanding continuum behavior and elucidating structurally and geologically important phenomena such as the propagation of acoustic and seismic waves, the quasi-static yield of granular media, the structural stability of soils and their liquefaction, and the non-invasive testing of geomaterials. The three and one half year effort has involved the Principal Investigator, a postdoctoral research associate, one Ph.D. research assistant and various M.S. research assistants supported in part by the AFOSR grant. This has involved the development and application of an improved computer simulation for idealized granular assemblages to the prediction of dilatancy, scalar conductivity and yield surfaces, continuing development of experimental methods for granular media, and the inception of related work on continuum-mechanical mixture theories for fluid-particle systems and porous media.
