Two series of fatigue crack growth rate (FCGR) tests using three point bend specimen with different integral knife edge designs are performed. Effect of elastic modulus on the measurement of fatigue crack length using compliance technique is analyzed.

• 用不同整体刀口设计的三点弯曲SE(B)试样做了两组疲劳裂纹扩展速率 (FCGR)试验 ,分析了弹性模量在柔度法测量疲劳裂纹长度中的影响。
