Thus, the stressconcentrationfactor due to the misalignment should be considered in the analysis of fatigue life of the local structures.
因此，在对局部结构进行疲劳强度分析时，应考虑错位对于应力集中系数的影响。
2
The concentration of alternate stress is a key factor of fatigue destruction.
而交变应力集中是疲劳破坏的一个关键因素。
3
The stressconcentration is a key factor causing fatigue failures. It is very important to make a quantitative research on the stress level and distribution characteristics of BHA.
