Optimum design of two-component composite armours against high-speed impact

This paper presents an effective methodology for the optimum design of two-component armours using Florence’s model and a new hybrid evolutionary solving technique. The proposed methodology provides a practical platform for the design of composite armours while accounting for various design criteria. The simulated design results are compared with those obtained from analytical design models. Comparison with the published experimental data shows that the present methodology, by taking into account all the design considerations, can produce more accurate results than analytical design methods. Moreover, unlike the conventional analytical design models, the present methodology allows the determination of optimal designs whereby both the armour materials and their thickness ratios are taken as integral design parameters.
