Research on the Damage of Warship Structure Subjected to Mixed Explosion Load
In order to calculate the damage effect of the surface warships subjected to modern anti-ship missile precisely, the solid modeling technology is applied firstly to simulating the penetration explosion of the anti-ship missile in this paper and initial detonation parameter of typical anti-ship weapon is solved based on mixed explosion theory for typical warhead and the explosion load is simulated by corrected sphere-feeding method. On that basis, material model and physical equation referred to numerical simulation of warship structure damage with the whole circuit described in detail and specifically. Also presented is typical computational example calculated by the general finite element procedure LS-DYNA which indicates qualitative coincidence from the impact effect to response tend between the numerical simulation results and experimental data and the method can be applied to the engineering calculation to analysis the damage characteristic subjected to penetration load which provides the basis for the research of ship blast-resistant.
