Ship structures are particularly prone to fatigue of material. As they sail wave loads and other cycling loads are acting on ship structural details and fatigue damage is being accumulated. Two main types of fatigue may be distinguished: high cycle fatigue, with moderate loads in big number of cycles, and low cycle fatigue, with high loads in medium number of cycles. Both can cause fatigue failure, but a combination of the two even more. However, the problem of combined HCFand LCFis yet to be understood thoroughly. This paper gives an introduction in the state-of-the-art HCFand simplified LCFcalculations. It points out to several models proposed for HCFand LCFcombination into resulting fatigue. Procedures are illustrated through one numerical example and results are discussed. © 2010 Taylor & Francis Group, London.
