Plastic Deformation of Granular Materials
Abstract
The deformation of granular materials occurs in a variety of applications: soil dynamics; avalanch flows; grain flow in bins. Our goal in this project is to develop a more complete understanding of the mechanics of granular flow. The project consists of two distinct but related phases. One phase is a study of the mathematical structure of constitutive relations used to model the granular medium. The research here is primarily concerned with the stability and well posedness of the evolution equations governing flow. Most of our efforts have concentrated on the Critical State Theory of Soil Mechanics, a mathematically attractive theory which has some success in modeling soil deformations. In particular, the Critical State Theory is reasonably successful at modelling the deformation of so called Cam clay , a type of clay tested by the Cambridge soil mechanics group in the late 1950's.
