Abstract

Effects of different design parameters on auxetic cellular sandwich defensive structure, like thickness, size and Poisson’s ratio of the honeycombs are studied. The process of a missile impinging on, and penetrating auxetic cellular sandwich structure and the failure mode of the structure under underwater explosion shock are simulated by nonlinear finite element software. Numerical results indicate that structural passive defense has been unable to deal with high speed projectiles. Compared with traditional defensive structures, the auxetic cellular sandwich defensive structure has better anti-shock performance, which will be enhanced by increasing the layers and Poisson’s ratio of the honeycombs. The structure is more suitable for underwater explosion protection.
