 note = {In the strength analysis of aircraft structures mostly made of metals, the strength of each individual structural member is evaluated by inputting the load of the structural member derived from an FEM (Finite Element Method) model of the entire structure into calculation formulas and design charts backed up by theories and experiences. On the other hand, in evaluating structures made of composites that have come to be used for primary structures recently, it has been clarified through the development of various products that there are limits to the simple extension of the conventional evaluation procedures used for metallic structures. It is not practical to obtain design charts only from elemental tests, because a great many design variables are required compared to metals. Consequently, it is necessary to establish a special method to analyze the strength of composites. Especially, to take advantage of the composite material merits such as lightweight, high-strength and so on, the development of a strength analysis method with high accuracy and high reliability is required. This report presents the strength analysis approaches for composite structures based on the microscopic fracture mechanics and the macroscopic progressive failure. In the microscopic analysis, the fracture process to a delamination is clarified by FEM analysis using microstructure models that can indicate differences between layers. In the macroscopic analysis, the tuning method between theoretical and experimental results based on the building block approach is applied to evaluate a global structure behavior by analysis code GENOA., 資料番号: AA0047427013, レポート番号: JAXA-SP-03-002},
