STRENGTH BEHAVIOR OF GRANULAR MATERIALS USING DISCRETE NUMERICAL MODELLING. PROCEEDINGS OF THE SIXTH INTERNATIONAL CONFERENCE ON NUMERICAL METHODS IN GEOMECHANICS, 11-15 APRIL 1988, INNSBRUCK, AUSTRIA. VOLUMES 1 - 3

A discrete particle model based on two dimensional disk-shaped elements is used to model granular soil behavior numerically. Simulations of standard geotechnical laboratory tests such as direct simple shear, triaxial compression and extension and one dimensional compression indicate that realistic nonlinear, stress-history dependent behavior can be obtained from the numerical model. However, use of circular-shaped particles allows particle rolling to dominate the observed behaviour. Inhibiting this particle rotation results in strength, deformation and volume change behavior more appropriate for "real" soil. (Author/TRRL)
