The model is developed based on a published experiment that was carried out by dropping a thin stiffened aluminum hollow box into the water from a prescribed height. The hydrodynamic impact causes damage in the middle of the plate which had an initial circular hole in the middle. The ABAQUS/CAE is used to model this experiment by using the Coupled Eulerian-Lagrangian method. The ductile damage property of the aluminum is defined to model the failure. The results show that the numerical simulation can predict the acceleration of the specimen close to that observed during the experiment. The simulation can also replicate the damage of the plate. A parametric study shows that one of the parameters that may affect the shape of the damage is the boundary condition definitions of the plate.
