Abstract

The micromechanical stress-strain model developed in an earlier study by Chang and Hicher (2005) is enhanced to account for the stress reversal on a contact plane and the density state-dependent dilatancy. The enhanced model is examined by simulating typical drained and undrained cyclic tests in conventional triaxial conditions.
