Abstract

Dynamic response of submarine foam samdwich structure by underwater explosion and its problem of fluid-structure interaction is analyzed.Changed rule of wall pressure in the face plate of the samdwich structure、incident impulse of the samdwich structure、velocity and acceleration of the face and back plate and sustaining counterforce are discussed,the influence of the dynamic response of samdwich structure by the material of the face plate is discussed.

Key words

submarine / samdwich structure / underwater explosion / dynamic response
