| Abstract: | Cyclic load-deformation curves of materials under tension-compression cycle and torsion cycle for different strain ratio were determined experimentally by using incremental step loading and total strain controlling technique in room temperature. Cyclic stress and stress ratio were obtained as functions of strain ratio. |

| Keywords: | stress strain relations strain ratio multiaxial stress mean stress |
