摘要

A comprehensive review of fatigue behavior and fatigue design of heavy section wind turbine castings made of ductile iron EN-GJS-400-18-LT is performed. Common metallurgical defects that are affecting fatigue behavior of this material were studied. Review of different researches on quantitative effect of chunky graphite and micro structure on fatigue behavior of EN-GJS-400-18-LT was performed. Finally, safe life design and damage tolerant design of heavy section wind turbine cast iron components were reviewed and compared with each other. It is tried to cover all the required points that should be considered in fatigue design of large EN-GJS-400-18-LT wind turbine castings.
