Introduction of Developing Fatigue Load Spectrum for Full-Scale Fatigue Test of Composite Aircraft
International Journal of Aeronautical and Space Sciences, 2020 This is a study on the loading spectrum for full-scale fatigue testing of composite aircraft structures. Fatigue tests are performed to confirm the durability and damage tolerance of a composite aircraft structure. In particular, as composite materials have fatigue life variance larger than that of metallic materials, it takes a considerable amount of ...
