内容記述 |
In this study, the deformation behaviors of F82H steel at 823 K under uniaxial and non-proportional loading conditions were described using a unified viscoplasticity model. The multiaxial creep?fatigue life was predicted using a strain energy damage parameter in collaboration with cycle-by-cycle concept. The creep?fatigue tested conditions includes tension holding and slow strain rate strain waveforms. Our findings showed that the cyclic deformation behaviors were well described using the unified viscoplasticity model. The creep?fatigue life was well predicted by the proposed energy-based model within a factor of 2. |
