Fluid-structure interaction by the method of characteristics
Abstract
Linearized formulations for the pressure loading on submerged structures are inadequate when applied to impulsive loads from strong underwater shock waves. The limitations are discussed and a new approach based on the method of characteristics is presented. A nonlinear, exact relation is obtained for the pressure loading on a compliant structure produced by a plane shock wave. The characteristics in the physical and state planes are described for the interaction of three dimensional, curved shock fronts with a structure. An approximate, nonlinear relation is obtained for impulsive shock loading on compliant surfaces by curved shocks.
