摘要
疲劳破坏对金属构件使用寿命影响极大。据研究,80%的构件破坏与疲劳破坏有关。分析疲劳现象产生的原因,并提出一些提高金属抗疲劳性能的措施,以期对提高金属构件的使用寿命有一些有益的参考。
Fatigue failure has enormous influence on service life of metal construction.According to research,about 80% of construction damage is related to fatigue failure .The causes of fatigue phenomenon are analyzed which help us to improve the performance of metal fatigue .It would be helpful to improving fatigue life of metal construction .
