Experimental Study of Nonassociated Flow and Instability of Frictional Materials. Attachment No. 1
This study presents the results of an extensive experimental investigation of granular materials at high pressures. Among the many types of experiments performed are drained and undrained triaxial compression and extension tests with an overall confining pressure range of 0.25 to 68.9 MPa. One-dimensional compression tests up to 900 MPa axial stress level were also performed. Major topics that were studied include: strain localization in triaxial extension tests; drained and undrained stress-strain and strength behavior from low to high pressures in triaxial extension and compression; instability of granular materials at high pressures in triaxial compression and extension; the determination of Skempton's pore pressure parameter B at high pressures; strain rate effects of granular materials at high pressures in drained and undrained conditions; examination of the effective stress principle at high pressures; particle breakage at high pressures; behavior of sands in one-dimensional compression tests at very high pressures; determination of values of k sub o, the coefficient of earth pressure at rest, at high pressures; evaluation of the elastic modulus and Poisson's ratio at high pressure levels; and correlations of high pressure soil behavior with stress-dilatancy, critical state, and input energy.
