| Abstract: | Based on experiments of low-cycle tension-compression, torsion and tension-torsion fatigue with holding time, the interactional law of creep and fatigue under multiaxial stress is proposed. And the micromechanism of equilibrium diagrams is analysed.Finally, a unite equation about fatigue life under multiaxial stress is concluded. |

| Keywords: | creep and fatigue multiaxial stress holding time |
