In this study computer control hydraulic geotechnical digital system (GDS) triaxial equipment used for the evaluation of shear strength behavior of the barind (expansive) soil in tensile stress path test. The testing program intense on the study of normally consolidated drained triaxial extension tests on sample size 50 mm diameter and 100 mm high compacted barind (expansive) soil. Testing was carried out at consolidation pressures ranging between 100–500 kPa. The unload-reloading tests were done at confining pressure 200 kPa for the determination of unload-reload model constants. The non-linear elastic model parameters for the compacted expansive soil were determined from these tests. An attempt is made to verify the model parameters by comparing numerical predictions with the experimental test results. Numerical analysis using hyperbolic model parameters indicated good agreement with the experimental results.
