| Abstract: | Using nonlinear finite element software MSC. DYTRAN, the dynamic response of ship under air explosion is calculated. The analysis of shock wave shows that results gained in the paper are reasonable. The dynamic response of the ship is studied through stress distribution, energy absorption of ship components and the shock environments factor, The paper has comes out conclusions which have some reference value to ship anti-explosion design. |
