To model the random cyclic strain life relations during low cycle fatigue, probability based cyclic strain life curves are suggested.
引入了概率循环应变—寿命曲线描述低周疲劳循环应变—寿命试验数据的分散性。
The stress strain curves displayed the characteristics of low yield point, continuous yield and no obvious yield point.
结果表明 ：其应力—应变曲线表现出屈服点低、连续屈服、没有明显的屈服点等特性 ；
