Abstract
The paper presents results of laboratory static and cyclic loading tests on Ottawa Sand. A variety of stress paths was used. The results are analyzed by elastic-plastic-work hardening theory. It is shown that the Mohr-Coulomb failure criterion, combined with an expanding elliptical cap can satisfactorily represent material behavior. The proposed model makes it possible to predict soil response to diverse stress paths from the results of hydrostatic compression and drained triaxial compression tests. The model is applicable to material behavior under both static and cyclic loading.
