摘要
本文讨论了用N-R模型预测做裂纹疲劳扩展的可行性，分别与铝锂合金，铜锌合金及16MnR钢的疲劳扩展的实验结果进行了比较，并提出了修正N-R模型的方法．
his paper presents a discussion on the feasibility of predicting the microcrack fatiguepropagation by use of the N-R model. A c0mparison is made betWeen the results of experi-ments on the fatigue propagation of Al-Li alloy,Cu-Zn alloy and 16MnR steel,and a methodfor revising the N-R model is introduced.
