In this paper, the hydroelasticity of two segmented ship models (Barge and KVLCC2) is investigated by experimental and numerical methods. A two-way Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA) coupled method is adopted and further validated its accuracy against experimental results. The current approach emphasizes the overall convergence between two solvers, maintaining a strongly coupled manner to comprehensively address the fluid-structure interaction phenomenon, including the added mass effect. A series of experiments of a segmented Barge and KVLCC2 under various wave conditions were firstly conducted. The motions of the models are measured and the displacement Response Amplitude Operators (RAOs) are calculated. The CFD-FEA coupled method is demonstrated in agreement with experimental results by comparing the numerical prediction with the tank test results in terms of motion, affirming the validity and robustness. Finally, the hydroelastic response is discussed and investigated. •The research employs a new Computational Fluid Dynamics (CFD)-Finite Element Analysis (FEA) coupled method, facilitating a comprehensive two-way coupling simulation for both two ships.•Experimental measurements are conducted on both the Barge and KVLCC2 ships under various wave conditions.•The research contributes significantly to a better understanding of ship hydroelastic responses, providing crucial support for advancements in ship design and safety evaluations with broad applications.
