摘要
通过国产核容器用钢Ｓ２７１的疲劳试验数据，采用统计分析的方法，获得了存活率Ｐ＝５０％和Ｐ＝９９．８７％的实用疲劳设计曲线，并与ＡＳＭＥ规范中相应的曲线进行了对比。
Two practical fatigue disign curves whose survial probabilities (P) equal to 50% and99. 87% respectively are developed by the method of the statistical analysis, based on the fatigue experimental results of the China-made steel 5271 for nuclear vessels. Furthermore, the fatigue designcurves obtained are compared with the corresponding curve in the ASME code.
