Quasistatic Mechanics and Materials Stability of Particulate Media
Abstract
This is the final technical report on a three-year program of research on the microstructural and continuum mechanics of granular media and geomaterials initiated under the AFOSR Particulate Mechanics Program. The research has led to the development of new theoretical models of microstructure, numerical simulation of granular assemblages, and development of new experimental techniques. The overall goal of the work is to provide a sound microstructural basis for understanding continuum behavior and elucidating structurally and geologically important processes such as the propagation of acoustic an seismic waves, the quasi-static yield of granular media, the structural stability of soils and the noninvasive testing of geomaterials. The research effort has been mainly devoted to the mechanics of dense suspensions and granular media in the quasi-static flow regime, with emphasis on shearing and dilatational instabilities. A summary is given immediately below of accomplishments and plans for continuing efforts.
