复合材料的疲劳性能数据比一般金属材料都要更加分散,通常采用威布尔分布进行统计处理。金属材料的疲劳研究也已提出了许多有用的研究方法,得到许多广为采用的疲劳性能表达式。但这些方法和公式是否能用于任何复合材料的研究是引人注意的问题。
Fatigue properties of composite materials than the average metal material should be more dispersed, usually using Weibull distribution for statistical processing. Fatigue studies of metallic materials have also proposed many useful research methods and many widely used expressions of fatigue properties have been obtained. However, whether these methods and formulas can be applied to any composite material is an attractive problem.
