Review of Small-crack Theory and Its Applications

  • 摘要: 疲劳小裂纹扩展行为是结构耐久性和损伤容限设计中关心的重要问题.着重对疲劳小裂纹扩展的微观机制、解析描述进行了分析和讨论:并评述了疲劳小裂纹理论在全寿命预测、耐久性分析和裂纹形成/扩展分界等方面的应用.
    Abstract: Fatigue small crack growth behavior is an important issue in structural durability and damage tolerance design.Small-crack theory is reviewed in this paper.Microstructural effects in small crack growth and analytical description of small crack growth rate are emphatically analyzed.Also the applications of small-crack theory to total fatigue life prediction,durability analysis,and crack initiation/propagation demarcation are briefly discussed.
