000004775 520__ $$2eng$$aComputational constitutive drivers are implemented for the numerical simulations of suction-controlled conventional triaxial tests on unsaturated soils using two elasto-plastic critical state based formulations: Barcelona model and Oxford model. Simulations are obtained from both explicit and implicit integration techniques. The algorithms support numerical analyses in a deviatoric stress plane by using a mixed control constitutive driver in conjunction with a Generalized Cam-Clay model, within a constant-suction scheme. Results from a series of suction-controlled conventional triaxial tests on 10-cm side cubical specimens of compacted silty sand, using a controlled stress and suction cubical test cell, are used for validation of both models. Matric suction states in the specimens were induced and maintained constant during testing via axis-translation technique.
