摘要
考察疲劳极限快速测定的精度,讨论了快速法的若干问题,提出用无损伤条件疲劳极限Snd构造的lgNp=ap+bplg(S-Snd)来代替常规的lgNp=ap+bplgS表达式等改进意见。
This paper discusses and evaluates the precision of the method for determining the fatigue limit by means of accelerated fatigue test.It put forword a suggestion that the no damage fatigue limit Snd forming the lgNp=ap+bplg(S-Snd) be used instead of routine lgNp=ap+bplgS and other improvements.
