摘要
综述了疲劳裂纹形成寿命和疲劳裂纹扩展寿命的预测方法,评述了各种不同预测方法的基本假设、估算步骤和特点,并对疲劳寿命预测方法进一步的发展方向作了展望。
The prediction methods of fatigue crack formation life and fatigue crack expanding life have been described in this article. The basic assumption, the estimation procedure and characteristic of different prediction methods have been evaluated as well, which has prospected the future development tendency of the fatigue life prediction method.
