| Abstract: | The prediction of high-frequency dynamic response of composite structures is one of key steps in the structural design of the aircraft and other vehicles. In order to make an accurate prediction, three methods are discussed. The energy finite element method is found to be suitable to obtain accurately the dynamic response of composite structures. In this paper, the energy finite element analysis and its applications for composite structures are reviewed. Some important issues for the further applications are suggested. |
