cyclic stress-strain meaning in English

周期应力-应变

The approximate polynomial method was based on neuber ' s method , the cyclic stress - strain responses and neuber ' s rule were treated as probabilistic curves , and the statistic characteristic was obtained from the approximate polynomial . the method is fast and easy for engineering application
近似的多项式拟合法在诺伯法的基础上，将循环应力应变曲线和诺伯双曲线视为概率曲线，通过建立近似多项式的方法，求得局部应力应变的统计特性，快速简便，适合工程应用。
The alloys , which were cold - worked followed by recrystallization annealing , display cyclic softening in the range of low strain because the cyclic stress - strain curve lies below the monotonic stress - strain curve , and show cyclic hardening in the range of high strain because the cyclic stress - strain curve lies above the monotonic stress - strain curve
在低应变范围，冷加工后经再结晶退火处理的错合金的循环应力一应变曲线位于单调拉伸曲线的下方，表现为循环软化;在高应变范围则位于单调拉伸曲线的上方，表现为循环硬化。
