COMPARISON OF SINGLE AND DOUBLE HARDENING CONSTITUTIVE MODELS FOR FRICTIONAL MATERIALS. NUMERICAL MODELS IN GEOMECHANICS. NUMOG III. PROCEEDINGS OF THE 3RD INTERNATIONAL SYMPOSIUM HELD AT NIAGARA FALLS, CANADA, 8-11 MAY 1989

Two constitutive models for frictional materials, one with a single yield surface and the other with two intersecting yield surfaces, are compared in terms of their capabilities to accurately capture the observed behavior of soils for various stress-paths and in terms of the ease with which they can be employed in large computer programs. Both models have been shown to capture the behavior of soils for a variety of stress-paths. The double hardening model may model the observed soil behavior with slightly better accuracy near the hydrostatic axis, but the single hardening model may be used with greater ease and economy in large scale computations.(a) for the covering abstract of this conference see IRRD 824029.
