Abstract
We propose a computational approach to study the response of compliant structures to impulsive loading due to impact on the free surface of a weakly compressible viscous fluid. The fluid flow is analyzed through the lattice Boltzmann method and the structural response by the finite element method. The time discontinuous Galerkin method is used to integrate the structural dynamics in time, and an explicit coupling strategy with the same time-step for the fluid and the solid is employed. Numerical results are compared to analytical and experimental findings for rigid and compliant wedges.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
