The similarity principle serves as the theoretical foundation for experimental research on scaled ship structures. While extensive studies have been conducted on global longitudinal responses using scaled hydroelastic segmented ship models, there is a notable gap in experimental research on scaled local ship plate structures. This research introduces a novel composite similarity principle tailored for local ship plate structur...

The ship hull girder model has been widely adopted in ship mechanics research such as small-scale and large-scale hydroelastic ship model experiments. Current design methods cannot seriously meet the structural rigidity requirement, and the distinction between the ship structural masses and the cargo masses is rather vague. This research proposes a simple and novel ship hull girder design methodology. The main novelties are th...
