Influence of different wave load sequence models on fatigue life prediction of ship structures based on fracture mechanics approach
FCP (Fatigue Crack Propagation) based fatigue assessments of a welded joint in a 2800 TEU container ship which sails on North Atlantic routes are performed. The Great-circle course with small variation of relative heading angle and a southerly course with large variation of relative heading angle ar...
