摘要

摘要: 金属材料疲劳裂纹扩展速率是对金属材料及其零构件含有裂纹体后安全服役评价及疲劳寿命评估的一项重要力学性能指标。基于金属材料疲劳裂纹扩展过程的不同阶段、闭合效应、应力比对疲劳裂纹扩展速率的影响等多个方面，对几种常见金属材料疲劳裂纹扩展速率模型的应用特点进行了对比分析，为安全设计及寿命评估时不同模型的选择应用提供参考。

Abstract: Fatigue crack propagation rate of metallic materials is an important index of mechanical property, which is employed for assessment of safe service and prediction of fatigue life for metallic materials and their corresponding components with cracks in them. In this paper, based on different stages of fatigue crack propagation of metallic materials, closure effect, influence of stress ratio on fatigue crack propagation and so on, characteristics of different models for fatigue crack propagation rate were compared and analyzed, which would provide reference for selecting appropriate models in safety design and life prediction.
