How to plot deviatoric stress vs axial strain in abaqus

 I am modeling drained triaxial compression test. I modeled soil as cylindrical part in abaqus. Bottom part of cylinder is fixed and on top displacement is applied. I used Dynamic/explicit steps. After running model and getting .odb file, couldn't match stress strain diagram from experimental results. I don't know whether i am calculating stress in right way or not. Can anybody guide me in this regard? Advanced thanks for your reply.
