Modeling and Simulation of Nonlinear Dynamic Response of Marine Platforms in Shallow Water and Surf Zone

Solomon Yim, PI

We examine the nonlinear coupled fluid-structure interaction characteristics of rigid and deformable structures of various sizes in shallow water and the surf zone. These structures include moored or free-floating platforms, barges, UUVs, AUVs, mines, etc.
