The Smoothed Particle Hydrodynamics (SPH) method is used to simulate the dynamics of the underwater explosion within the two-dimensional square metal vessel. The SPH particles well represent detonation gas of an explosive charge, water confined in the vessel, or metal surrounding water as the vessel. The shock wave propagating in water impacts the metal wall and deforms the vessel. Finally, the vessel is ruptured at the corner by the impact of the underwater explosion. Furthermore, the impact passing through the metal wall is simulated and eventually causes the shock propagation in the next room within the vessel. The present simulations clearly demonstrate the advantage of SPH method reproducing the damage of the explosion accident including the coupled fluid-structure interaction.
