In the low cycle plasticfatigue period, the fatigue progress life Nfcan al - so be increased by 1 time.
在低周塑性疲劳阶段构件的疲劳开裂寿命仍可提高1倍左右。

In this paper the mechanism of plasticfatigue crack growth (PFCG) was analyzed and an appropriate criterion was proposed. Elastic-plastic (incremental) finite-element method was used to study PFCG.
本文分析了裂纹塑性疲劳扩展的力学机理，提出了裂纹塑性疲劳扩展的判据。
