Abstract

Abstract: This paper establishes a twodimensional fully nonlinear numerical wave tank for studying the interaction between focused waves and floating elastic plate. The secondorder Stokes wave velocity is given to generate the input wave. The mixed EulerianLagrangian approach is applied to track the transient free and plate surface. A series of modal functions with freeend conditions are adopted to interpolate the displacement, and then the fourthorder RungeKutta scheme is used to refresh profile and velocity potential. The numerical model is verified with existing numerical and experimental results. The effects of the design parameters on the responses are systematically analyzed.

Key words: very large floating structure, focused waves, time domain fully nonlinear, hydroelastic responses, higherorder boundary element method
