In this paper a simple analytical method is proposed to estimate an elastic–plastic strain and stress in the plastic zone ahead of the tip of a stable growing fatigue crack. Analytical estimations are compared with experimental results from digital image correlations (DIC) and integrated finite element (FE) analyses taken from literature. A fairly good agreement is demonstrated between the proposed analytical method and the DIC and FE data.

模式 I 中疲劳裂纹前弹塑性应变和应力的估计

在本文中，提出了一种简单的分析方法来估计稳定增长疲劳裂纹尖端之前塑性区中的弹塑性应变和应力。分析估计与来自文献的数字图像相关性 (DIC) 和集成有限元 (FE) 分析的实验结果进行比较。建议的分析方法与 DIC 和 FE 数据之间显示出相当好的一致性。
