A flexible vertical sheet in waves
- Univ. of Otago, Dunedin (New Zealand)
The problem of a vertical elastic sheet subjected to a train of ocean waves in infinitely deep water is solved. The sheet is assumed to be thin and governed by the Bernoulli-Euler equations, and to extend from the water surface to a finite depth. The solution utilizes the Green`s function for water waves and the transformation of the Bernoulli-Euler equation to an integral equation. The model predicts that there will be substantial reflection when the sheet is held rigidly at the top end and penetrates the water to a significant fraction of the wavelength. Resonances at which the reflection is reduced, or is zero, also exist for certain values of the stiffness, mass and frequency. A sheet which is free at both ends does not reflect significantly for any values of mass, stiffness or depth of the sheet.
