多轴应力下蠕变疲劳交互作用

Effect of Combined Fatigue and Creep under Multiaxial Stress

    摘要
  • 摘要: 通过对不同应变保持时间下的拉压、扭转和拉扭组合高温疲劳试验,得到了多轴应力下蠕变疲劳交互作用的特性及断口的微观相图,并且提出了多轴应力状态下疲劳寿命的统一方程.

     

    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.
