Numerical Simulation for Impact of Elastic Deformable Body against Rigid Wall under Fluid Dynamic Force

Abstract

Numerical simulations of fluid-elastic body interaction problem are presented. In the verification of elastic body model for damped free vibration in stationary fluid, the present solutions agree reasonably well the analytical ones. We can successfully simulate flows around a largely moving and deforming elastic body and collisions of the elastic body with rigid surface under the fluid dynamic force by using the elastic body model. In future work, the elastic body model should be validated through comparison between the numerical result and experiment.
