摘要
概述了结构疲劳破坏寿命特性概率统计方法研究的发展及理论基础 ,从常规疲劳特性P -S -N曲线的研究应用、疲劳裂纹扩展率统计模型研究现状以及损伤力学理论在疲劳强度中的研究展望来综述现有随机疲劳破坏寿命分布统计特性曲线的研究方法和工程应用 ,同时介绍该领域研究的新成果新方法 。
The development and basic theory are summarized on investigation of random fatigue life characteristics.The life distribution statistical investigation methods and engineering applications are generalized,based on the present researches on fatigue characteristics P-S-N curves and fatigue crack growth statistical model as well as the development of the damage mechanical theory in the investigation process of structure fatigue strength.Characteristic curves of random fatigue failure,and new results and new methods in this research field are introduced .Opinion is given to further developing key and tendency on the randomness research of fatigue failure.
