纖維強化疊層複合材料以其質量輕、強度高等優點,使得此一材料廣泛應用於航太、軍事等結構。這類結構在使用的過程中除承受靜動態荷重之外,亦有可能承受爆炸荷重。為了達到材料最有效的應用,本研究將針對複合層板承受爆炸荷載的反應進行分析與最佳化設計。
有鑑於一般有限元素分析 (FEA) 通常僅做單一案例分析,鮮少配合程式進行最佳化分析,本研究將遵循Powell方法之精神,透過撰寫Python腳本 (script) ,實現以Abaqus做為工具的最佳化方法,探討複合材料層板受爆炸衝擊的疊層角度最佳化問題,提供產品製造者以更有效率的方式完成品質更好的產品設計。
Laminated fiber-reinforced composite materials are widely used in aeronautic engineering, military engineering, etc. thanks to its advantages like light weight, high strength and so on. These structures may stand for the blast loading besides normal static or dynamic loading. To get the most efficient use of materials, this research would focus on the analysis to the responds for the composite laminates under blast loading, and optimize its design.
A common finite element analysis (FEA) usually focuses on the single analysis without aid by programming to perform an optimization analysis. So this research follows the spirit of Powell's method to achieve the optimization for composite laminates under blast loading by using Python script controlling Abaqus. With the algorithm developed in this thesis, the manufacturer can make better design for product in a more efficient way.
