INVESTIGATIONS OF THE QUASI-STATIC AND DYNAMIC RESPONSE OF GRANULAR SOILS.
Abstract
The report describes experimental studies of shock-induced sustained-amplitude stress waves in soil. A general analysis is made of wave propagation in a cylindrical bar. The mathematical model includes stress relaxation and radial inertia factors. Also included is analytical interpretation of unloading wave propagation. Unloading waves were generated experimentally by suddenly unloading a previously loaded cylindrical specimen. The analysis results in a theory which accounts for longitudinal, axial, and radial shear modes. Preliminary results are presented of experiments involving earth shock with spherical symmetry. Quasi-static isotropic compression tests and their associated problems are discussed. (Author)
