Underwater Explosion Damage of Ship Hull Panels
Keywords: Underwater explosion, failure mode, hull panel, shock loading, finite element model, deformation
AbstractUnderwater explosion is a major threat to ships and submarines in a war environment. The prediction of the mode and the extent of the failure is an essential step in designing for shock loading. The localised failure in a hull panel is severe compared to the global response of the ship. In this study, an attempt has been made to predict the response and failure modes of three types of hull panels (flat, concave, and convex). The shock loading on the hull panel has been estimated based on the Taylor's plate theory. The numerical analysis has been carried out using the CSAIGENSA (DYNA3D) code that employs nonlinear finite element model.
