VERIFICATION OF THE ELASTOPLASTIC-VISCOPLASTIC BOUNDING SURFACE MODEL FOR COHESIVE SOILS

抄録

Verification analyses associated with the elastoplastic-viscoplastic bounding surface model for isotropic cohesive soils, which was developed in an earlier paper, are presented. Following a brief overview of its theoretical aspects and numerical implementation, the simulative and predictive capabilities of this model are described. It is shown that the model can realistically simulate and predict drained and undrained creep and stress relaxation, strain rate effects, and secondary consolidation.
