摘要 提出了以裂纹顶端延伸位移幅度为驱动力参量的疲劳短裂纹扩展速率描述方法,在小变形情况下与Nisitani方程是一致的.以正火15MnVNq钢试验数据进行了验证,对疲劳短裂纹扩展速率描述结果表明,该方法是合理有效的. The crack-tip extension displacement range is utilized to describe the rate of short fatigue crack propagation. The test result of normalized 15MnVNq shows that the proposed method is effective and accurate.
