fatigue endurance limit

基本解释

But steel alloys subjected to cyclic stress levels below their endurance limit rarely fail as a result of fatigue.
但是在钢铁合金的耐用度限制下，作为疲劳的结果，它们经受周期压力级别很少失灵。
Care should be taken when using the idea of an endurance limit as a "safe stress" below which fatigue will not occur.
用疲劳极限作为低于它将不出现疲劳的安全应力时，必须要注意。安全应力时，必须要注意。
After the endurance limit of fatigue is obtained, the other parameters of mater ial can be fitted by using the least square method according to the experimental results mentioned above.
在求得疲劳极限后，再根据上述试验结果以最小二乘法拟合上述其它材质参量。

But steel alloys subjected to cyclic stress levels below their endurance limit rarely fail as a result of fatigue.
