Paris law can reflect the failure mechanism of materials and is usually used to be a method to predict fatigue life or residual fatigue life. But the variable which can represent the health of machine...
对裂纹扩展规律Paris公式物理本质的探讨
2007/7/28
摘要首先讨论了著名力学家K. Krausz和A. S. Krausz关于Paris公式物理本质研究的成果，从材料的微观结构和裂纹尖端的应力场出发, 应用位错动力学理论、热激活能理论和速率过程理论对疲劳裂纹扩展规律进行了微观到宏观的探讨，最终推导出疲劳裂纹扩展速率的一个解析表示式. 该式严格地定义了Paris公式的两个试验常数，赋予了Paris公式明确的物理意义，从而真实地揭示了Paris公式的物理...
