摘要
对疲劳缺口系数Ｋ＿ｆ的定义、影响因素及典型表达式的建立作了简单而系统的回顾和综述，对各种Ｋ＿ｆ公式的产生和使用按点应力模型、断裂力学模型和场强法模型等作了一些评述。
The fatigue notch factor is a significant coefficient for notched strength prediction. In this papertwo main definitions and primary influential factor of the fatigue notch factor are discussed.According to their es-tablishments,most of formulas which are commonly used can be classified into three kinds of model---generalpoint stress model,accepted fracture model and promising stress field intensity model.Based on these three mod-els,the main formula of the fatigue notch factor are reviewed and discussed.
