As the raked bow is a common design, it is of great importance to accurately analyze the crashworthiness of a ship’s side structure subjected to raked bow collision. The deformation mechanism of ship side plating is analyzed in this paper, which is based on the plastic deformation theory and numerical simulation technology. The deformation mode and energy dissipation of the side plating during the collision process are obtained through numerical simulation and code LS_DYNA, and the deformation model of side plating is established. The analytical expression of the resistance of side plating deformation is derived and verified by the numerical simulations. The results match well, proving that the proposed analytical method can benefit the ship side structure’s crashworthiness during the structural design phase.
