碩士 === 國立成功大學 === 土木工程學系碩博士班 === 101 === 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.
