Anti-warship missile penetrating to a warship and ship's inner-explosion damage

With help of finite element program, the ship's structural changing and overloading response were analyzed in process of a missile pentrating to a ship. The position information of the warhead of the missile in the cabin of the ship was obtained, it gave rise to the initial condition of the ship's inner explosion. Then, the cabin model was designed and its inner-explosion tests were conducted. The study results showed that the anti-warship-missile penetrates the shipboard, making large overload to fuse and realizing inner-explosion; the cabin structure is collapsed when it faces high detonation wave; owing to weak strength of welding positions, the high pressure leaks from there; due to good absorption of shock wave energy, thick board is not broken but cupped partially; thick board can prevent the vital cabin from damaged even though the ship suffers from inner explosion.
