疲劳延性系数 meaning in English
fatigue ductile coefficient
Examples
- Fatigue strength coefficient decreases linearly during the cyclic course ; fatigue strength exponent increases ; fatigue ductility coefficient first goes up till the maximum value at 50 % total life , and then goes down ; fatigue ductility exponent decreases during the first half cycle till its minimum value at 50 % total life and then increases in the rest cycle course ; cycle strength coefficient and cycle strain hardening exponent both decrease during the total cycle course
结果表明： 6个基本疲劳特性参数在循环过程中都呈显出规律性变化。疲劳强度系数呈线性减小趋势；疲劳强度指数呈线性增大特征；疲劳延性系数是一个先增后降的过程；而疲劳延性指数随循环进行由初始减小到逐渐增大；循环强度系数和循环应变硬化指数在整个循环过程中都趋于减小。
