Optimization of S-N curve fitting based on neighborhood rough set reduction with improved firefly algorithm

Yangjinyu Li, Li Zou, Zhengjie Zhu

S-N curve fatigue samples of titanium alloy welded joints have such a comparatively significant scatter, that results in the issue that the fatigue life prediction accuracy is not optimal. In this work, the titanium alloy welded joints'…

S-N curve modeling method of Aluminum alloy welded joints based on the fatigue characteristics domain

Li Zou, Xinhua Yang, Jianrong Tan, Yibo Sun

The scatter degree of the fatigue samples is reduced when the nodal force based structural method is used for steel welded joints, while it is still high for aluminum alloy welded joints. Statistical method and rough set theory is used to…
