ABSTRACT

Finite elements modeling data is fitted to the results of experimental undrained monotonic and cyclic isotropic triaxial tests. The model can predict the accumulation strain /stress, and pore pressure in undrained state. For determination of material constants, the first cycle (loading-unloading) is performed step-by-step, using Hardening-Soil model for undrained soil, then for the cycles greater than one, the Behavior of the soil is simulated as a pseudo creep (Soft-Soil-Creep model, here) where the number of cycles N is considered equivalent time. The prediction of model is compared with experimental results from monotonic and cyclic undrained isotropic triaxial tests. Good correlation exists between predicted and experimental response.

Keywords: Triaxial undrained, cyclic tests, Hostum sand; Pseudo cyclic creep model, Explicit model, PLAXIS.
