Analytical model of bottom plate torn by a cone-shape rock during ship grounding accident

A theoretical method for plate tearing by a rigid cone was developed. The studied model is an idealization of ship grounding damage. The observed mode of deformation was idealized as a simplified kinematical admissible deformation mode,and the rate of internal energy dissipation in friction,stretching,bending and fracture was quantified accordingly by analytical expressions. Based on the upper-bound theorem,the plate tearing resisting force in the moving direction of the cone was calculated by the proposed analytical formula. The analytical results were compared with a series of Muscat-Fenech experimental results,and they agree reasonably well. The non-linear finite element program LS_ DYNA was used to simulate several grounding scenarios of a typical ship double bottom structure running aground on a cone-shape rock. By adopting equivalent plate thickness,the analytical method proposed was verified by the simulation results. The analytical calculation formula obtained can be used to calculate and assess the crashworthiness of a ship during its design phase.
