Dynamic response of a submarine foam sandwich structure subjected to underwater explosion

Dynamic response of a submarine foam samdwich structure subjected to underwater explosion and its problem of fluid-structure interaction were analyzed.The varying law of the wall pressure of the front face plate of the sandwich structure,the incident impulse of the sandwich structure,the velocity and the acceleration of the front face and back plates as well as the sustaining force of the back plate versus the different relative mass densities of the foam layer were discussed,the influence of the material of the front face plate on the dynamic response of the sandwich structure was discussed.
