Experimental Study of Nonassociated Flow and Instability of frictional Materials
Experimental investigations and analyses have been performed to study the behavior of granular materials with respect to their nonassociated flow and instability under certain loading conditions. All experiments have been performed in triaxial compression and extension at high as well as at low confining pressures. 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 sand 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; correlations of high pressure soil behavior with stress-dilatancy, critical state, and input energy; static instability and liquefaction of loose fine sandy slopes; stability of granular materials in post peak softening regime; instability of dilating sand; and creep effects on static and cyclic instability of granular soils....
