| 摘 要： | 为描述腐蚀对结构材料疲劳性能的影响，本文首先定义了等效腐蚀损伤的概念；其次通过结构件预腐蚀前后的疲劳寿命试验，得到了等效腐蚀损伤数据，并选取正态分布、从Gumbel第一型极值分布、Logistic分布、双参数威布尔分布及三参数威布尔分布等五种分布形式，对其进行了统计特征的研究。结果表明，等效腐蚀损伤较好地服从三参数威布尔分布。

| Abstract: | In this paper equivalent corrosion damage was put forward firstly to describe the effect of corrosion to the fatigue performance of structure.And secondly through fatigue tests with structure specimens before and after pre-corrosion,the equivalent corrosion damage data was got,and then statistical investigation for it has been conducted with normal distribution,Gumbel distribution,Logistic distribution,two parameters Weibull distribution and three parameters Weibull distribution.The result shows that equiva... |
