| 1. | No evidence of fatigue crack extension was detected in the silver memorial bridge nor the fremont bridge .
在西尔费纪念桥和弗里蒙特桥都没有检查出疲劳裂纹扩展的证据。 |
| 2. | At least 60 bridge sites developed fatigue cracks as a result of out-of-plane distortion in a small gap .
至少有60座桥上出现的疲劳裂纹是由于小间隙处的面外变形引起的。 |
| 3. | Thus the fracture likely initiated from fatigue sharpened cracks originating from slag and void in the plug welds .
因此，断裂可能是由于从塞焊焊缝内的焊渣和气孔外形成的尖锐的疲劳裂纹而产生的。 |
| 4. | The theoretical and experimental results for the 7075-t6 wol specimens presented above both show that intermittent proofing provides early warning of impending failure due to the growth of fatigue cracks .
以上所讨论的7075T6WOL试样的理论和试验结果都证实：对因疲劳裂纹扩展即将引起的破坏，用间歇验证试验法可以作出早期警报。 |
