  • Abstract

    One of the main ways that ship structures fail is through fatigue damage. Usually, this type of damage starts at the structure's weak points, ‎such as welded joints, cracks, and concentrated stress points. The primary focus of this study is fatigue damage that ships experience over ‎their operating lifespan as a result of cyclic stress, especially from waves. Though some are merely approximations, there are numerous ‎ways to different sea state situations. The most popular methods will be reviewed, including their strengths and weaknesses. Some of the ‎major theoretical methods discussed are energy spectrum methods in frequency and time domains, which estimate fatigue life based on ‎wave-related energy, amplitude, and wave loads. In addition, the evaluation of cyclic stress in specific hull girder and welded joint features ‎through finite element analysis will be presented to quantify the maximum stress range for future fatigue testing.
