针对传统有限差分法得到的da/dN-Δ K数据离散性大的问题，提出了用积分法确定疲劳裂纹扩展速率。结果表明，积分法所得结果与试验结果吻合较好，且所得疲劳裂纹扩展速率更为严格。
In allusion to the great dispersion of the data d a /d N —Δ K obtained by the traditional method of finite difference, the method of integration is proposed to determine the growth rate of fatigue crack. The two methods are compared and it can be shown that the result given by the method of integration is consistent to the experimental result satisfactorily, and the growth rate of fatigue crack will be more rigorous.
