查询词典 fatigue limit

In the research of high cycle fatigue of concrete, the test means of cyclic loading between the set constant or various upper limit and low limit of force or stress has been extensively used. But this kind of test means can't be used to study the behavior of concrete low cycle fatigue under large strain.

同时高周疲劳问题研究中使用的在设定的力或应力的上下界限之间重复受力的试验方法已无法用于混凝土高应变低周疲劳性能的试验研究。

The stress concentration factor is introduced to modify the fatigue limit and a practical damage evolution equation is established.

引入应力集中因子修正疲劳极限，提出一种实用有效的损伤演化方程。

Center sill and body bolster are important component of gondola car, and it is a big threat to the safety operation when the component occurs fracture, so the fatigue limit with high confidence level and high reliability must be gained first.

中梁和枕梁是敞车的重要组件，如果该组件发生断裂，会对行车安全构成极大威胁，所以首先要得到该组件具有高置信度、高可靠度的疲劳极限。

The Ti-Ni SMA spiral spring had longer fatigue limit when heat treatment at 773K.

在所使用的场合中，这些弹簧常受热循环应力的作用，易于疲劳损坏。

The characteristics of fatigue cracking, in rib to crossbeam joints, rib to deck plate joints and rib to rib joints, are understood by the analysis of the test results. The regression line and 95% confidence lower limit of △σ-N curves are given for these joints. Their available fatigue strength is suggested for fatigue design.

通过对试验结果的分析，了解了纵肋与横梁连接、纵肋与盖板连接和纵肋与纵肋连接的疲劳开裂特点，给出了这些连接细节△σ—N曲线的回归线和95%置信下限，提出了疲劳设计时可采用的疲劳强度。

The fatigue limit of the S-N curve is found to be about 30% of the ultimate static failure stress, which validates the value suggested by the UK guidance.

其疲劳极限值约为静载作用下极限界面主应力的30%，与英国规程中的规定相符。

Endurance—Alternate term for Fatigue Limit.

耐久力—疲劳极限的另一个术语。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
