Abstract [en]

The paper discusses challenges in modeling and quantification of hydroelastic effects in panel-water impacts and summarizes results from numerical and experimental studies. Kinematic and inertia related hydroelastic effects are discussed and exemplified in relation to pressure distributions and structural responses. Hydroelastic effects are quantified by comparing hydroelastic results with rigid/ quasi-static reference results where the hydrodynamic loading is treated as unaffected by the structural deformation (rigid) and the structural response is treated as unaffected by structural inertia (quasi-static). The formulation of non-coupled reference solutions in experimental studies is particularly challenging and the paper addresses this problem by outlining a semi-empirical approach to reach such solutions. For those impact situations were the hydroelastic interaction seems to have a significant effect, it is found both numerically and experimentally that the hydroelastic effects are amplifying the structural responses in comparison to the rigid/quasi-static reference solutions. Two approaches for characterization of impact situations regarding the involved hydroelastic effects in relation to panel properties and impact conditions are discussed and exemplified. These approaches can tentatively be used to evaluate the hydroelastic effects in design situations.
