Abstract

Sand, which is generally considered as non viscous exhibits time dependent behavior. This last assumption is confirmed for dry and saturated Hostun RF sand in the small and medium strain range using different apparatuses (triaxial, hollow cylinder) and stress paths. Experimental results show that the creep strain is not negligible and can reach 10% of the monotonic loading strain. In addition, behavior after creep or relaxation periods is much more rigid than without these periods. One main conclusion is that the classical elastoplastic modeling is a rough approximation for specific stress path, which can exist in the ground, because it does not introduce time dependent behavior.
