Abstract
In this paper, slamming experiments at constant velocity are presented. The hydraulic shock test-rig enables fast experiments at quasi-constant velocity during a water entry of a wedge. This approach provides results more suited for validation of numerical models. The objective of this paper is to discuss the influence of panel stiffness on pressure and strain, for an aluminum wedge with a deadrise angle of 30° and for various velocity levels. Information on wet surface expansion velocity is inferred from the detection of the threshold pressure on the placed sensors. The experimental evolution of the maximum pressure and wet surface expansion velocity is in good agreement with analytical results and can be predicted by semi-analytical formulas.
