An Integrated Approach to the Stress Analysis of Granular Materials


Up to a very recent time, it has been difficult or impossible to perform exact analyses of any realistic field problem in soil mechanics or soil engineering even when a linearly elastic behavior was assumed for the soil involved. As a consequence, analyses in soil mechanics have been restricted to extremely idealized physical situations including linearly elastic behavior (uniform loads or rigid footings at the surface of semi-infinite elastic continua, for example) or to problems of plastic equilibrium. The latter also include greatly simplified geometries and an idealized material behavior. In part, because of these mathematical difficulties, little attention has been paid in soil mechanics to the deformational properties of soil other than at failure, or for the purpose of getting equivalent elastic moduli.

The research outlined here was undertaken under NSF Grant GK-626 in the Division o£ Engineering and Applied Science at the California Institute of Technology. This work forms a part of a general investigation into constitutive relations for soils and their use in practical problems. This research grant is under the general supervision of Professor R. F. Scott. A portion of the participation by Dr. R. A. Westmann was supported by the College o£ Engineering, University of California, Los Angeles, California.
