Many existing models for sand are not capable of describing the behavior ranging from very low to very high confining stresses. In this study, a generalized plasticity model is extended to capture the dilatancy and strength properties of sand under a wide range of stress levels. The model is validated with the experimental results of several different types of sand under drained conditions. 000004951 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000004951 653__ $$aConstitutive model, Stress level, generalized plasticity, dilatancy, dense sand, loose sand 000004951 7112_ $$a15th ASCE Engineering Mechanics Division Conference$$cNew York (US)$$d2002-06-02 / 2002-06-05$$gEM2002 000004951 720__ $$aLiu, Huabei$$iLing, Hoe I. 000004951 8560_ $$ffischerc@itam.cas.cz 000004951 8564_ $$s683121$$uhttp://invenio.itam.cas.cz/record/4951/files/603.pdf$$yOriginal version of the author's contribution as presented on CD, . 000004951 962__ $$r4594 000004951 980__ $$aPAPER
