Hypoplasticity for soils with low friction angles

Abstract

Abstract Hypoplasticity has been proven to be successful in reproducing the mechanical behaviour of sands. However, in case of clays the incremental stiffness in shear is predicted too low. An investigation of the hypoplastic equation based on the analysis of response envelopes reveals the reason of this deficiency. An improvement is proposed and compared with experimental results for Rio de Janeiro clay.
