摘要
概述了含缺口构件疲劳寿命预测方法,重点介绍了名义应力法、局部应力-应变法和应力场强法,总结了这些方法预测含缺口构件疲劳寿命的原理、应用方法、适用范围、优缺点,并介绍了近几年来这些预测方法在国内外的研究现状和进展。
The life prediction methods of notched specimen are reviewed,especially on nominal stress approach,local stress-strain method and stress field intensity approach. It introduces the principles、application methods、range of application、advantages and disadvantages of the fatigue life prediction method of notched specimen. And present research status and development are introduced.
