Abstract

Abstract

Broadside defensive structure is important for naval vessels to maintain vitality. A novel broadside defensive structure with macro negative Poisson's ratio is proposed to achieve higher anti-shock and anti-blast performance by design of auxetic honeycomb configuration. The process of an anti-ship missile impinging on and penetrating broadside structure is simulated by nonlinear finite element software. Effects of different design parameters on broadside structure, like auxetic honeycomb configurations, materials, sizes and thickness of honeycomb cell, are studied and compared. Numerical results indicate that counter-impingement capacity can be improved by adoption of auxetic broadside structure, and honeycomb cell with negative Poisson's ratio is better than that of common honeycomb cell on anti-blast performance.
