Karmakar, D. and Guedes Soares, C. (2011), “Wave interaction with moored floating elastic plate in the presence of end wall”, Coastal and Maritime Mediterranean Conference, 22-24 November, Tangiers, Morocco

Wave scattering by a finite floating elastic plate connected with mooring lines at its end and with the presence of a wall is analyzed in detail based on the linearized theory of water waves. The solution of the physical problem is obtained using eigenfunction expansion method and by the application of orthogonal mode-coupling relation. The hydroelastic behaviour of the floating elastic plate is investigated by analyzing the effect of the stiffness of the mooring lines on the reflection and transmission characteristics of the gravity waves. The vertical displacement response of the elastic plate are computed and analyzed to understand the effect of mooring on the wave motion below the plate. It is observed that with the increase in the stiffness parameters of the mooring lines the vertical deflections of the floating elastic plate is reduced and with the increase in the distance of the end wall the vertical deflection within the floating elastic plate and the end wall increases. This suggests that the deflection in the transmitted region can be reduced due to the presence of moored floating elastic plate.
