应变硬化指数 meaning in Chinese
strain hardening exponent
strain hardening index
Examples
- Strain hardening index
应变硬化指数 - N metallic materials - sheet and strip - determination of tensile strain hardening exponent n - values
金属薄板和薄带拉伸应变硬化指数 - Iron and steel - method of determination of the tensile strain hardening exponent n of steel sheet and plate
钢铁.薄钢板和钢板拉伸应变硬化指数n的测定方法 - 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。
