dc.description.abstract | Recently, reactive materials are developed to improve efficiency of penetrating munitions. These materials are usually manufactured cold spraying, and can be utilized both as explosive and structure due to its varying sensitivity according to strain rate. However, shape of the material is difficult to determine because of its manufacturing constraints and mechanical behavior. In this research, shape of the reactive material structure is derived through finite element analysis and topology optimization. Penetration analysis of the munition considering mechanical characteristics of explosive and the reactive material is performed using LS-DYNA and impact resistance of the munition is assessed. Based on the analysis result, topology optimization of the reactive material structure considering its manufacturing limitations is performed using artificial bee colony algorithm. The optimum structure satisfies manufacturability, and impact resistance of the munition is improved significantly. | - |
