摘要
在文献［１］的基础上，提出了金属构件疲劳裂纹扩展尺寸的通用简便计算式，并用６种钢的疲劳裂纹扩展数据进行了验证，达到了工程的计算精度。应用范围广泛。
Based on article,author established a group of simplified and general calculation formulas for sizing the propagation of fatigue cracks in metal structural units and its components.This formulas have been verified through published propagation data of fatigue cracks regarding 6(six)categories of steel,showing the calculation formulas have reached well known engineering accuracies and could be widely applied.
