Recently, in the trend of achieving both high strength and lightness at the same time is essential in the materials, making the structure of aircraft, the development are being developed, being lighter and harder materials that can be made to fit the target shape and forming process of transportation parts. In particular, aircrafts are exposed to frequent vibrations and strong external forces during operation. Materials must be applied by considering both the static material properties, which are unique properties of existing materials, and, Incidentally, the dynamic material properties, must be decided carefully. To meet the above requirements, this lab conducts research to verify the high-speed properties of high-strength steel and aluminum materials used in the aircraft through experiments, finite element analysis, and various deep learning techniques. In addition, conducting comparative verification with high-speed forming experiments and finite element analysis that can incorporate dynamic properties evaluate better formability and strength compared to existing forming methods, and a method of forming that can be applied to aircraft was developed.
