| 摘 要： | 本文首先引进了反映结构、材料特性的模糊疲劳失效集的概念,进步研究了模糊交变应力作用下所造成的结构的模糊疲劳损伤集,并定义了两个模糊集之间的一种模糊关系来刻划结构疲劳损伤的程度及其可能性分布,最后简述了该理论在海洋石油平台桩腿疲劳损伤分析中的应用。

| Abstract: | This paper introduces the concept of fuzzy fatigue failure sets which reflects the fuzziness of structure and material, the structure's fuzzy fatigue damage sets caused by fuzzy, alternative load, defines the fuzzy relationship between two fuzzy sets to describe the degree of fatigue damage and its possibility distribution. A brief discussion has also been made of the application of the theory to analysing the offshore platform leg sfatigue damage. |
