| Abstract: | The dynamical response of ship structures subjected to underwater explosion shock waves is a mechanical problem which must be taken into account in engineering design of anti-shock ship structures. The dynamical response of a surface war ship has been simulated with the code MSC.DYTRAN. The dynamical response characteristics of the ship is studied through the structural damage deformation, energy absorption by ship components and the shock environments factors. |
