Paper No: OMAE2013-10443
... A dynamic analysis of axially loaded plates with intermediate fixities is presented. The underwater part of a craft is modeled as a lightly damped flexible plate, which rises out of the water and slams against it at a large vertical velocity. This causes highly localized hydrodynamic impact...
