摘要
本文基于Coffin-Manson原理,阐述了用于估算低周腐蚀疲劳寿命的5个计算模型,用这些模型拟合了7种工程材料的试验数据,讨论了拟合结果、模型精度和各自的适用范围。
Five computational models based on Coffin-Manson rule are presented to predict corrosion fatigue life in low cycle regime. Fatigue test data of seven engineering alloys in air and corrosive environments are fitted to these models.The fitting results, the accuracy of the models and the scope of their applications are discussed.
