| 摘 要： | 介绍４５钢在不同扭转预应力变下的低周疲劳性能，包括循环应力－应变特性，循环硬化软化特性及低周疲劳寿命的研究工作。结果表明，扭转预应变降低周疲劳寿命，循环应力随扭转预应变的增大而增大。

| Abstract: | This paper investigates the low cycle fatigue behaviors of steel 45 under torsional prestrain,including low cycle fatugue life,properties of cyclic stress strain,and properties of cyclic hardening and softening.The results show that low cycle fatigue life is reduced and cyclic stress is raised by torsional prestrain raising. |

| Keywords: | torsion prestrain low cycle fatigue fatigue life |
