Predicting wind induced aerodynamic forces on aerospace structures is usually computationally expensive even for powerful computational facilities. For these unsteady computations, adaptive finite element technique may reduce the computer time and storage while keeping a desired accuracy. In this report, the p-version adaptive finite element method is implemented into a standard benchmark problem, the computational how around a circular cylinder, to compute aerodynamic forces. The error distribution for velocity is ...
With the resurgent interest in flight vehicles such as the High-Speed Civil Transport (HSCT), the X-33 Advanced Technology Demonstrator, the Reusable Launch Vehicle (RLV), the Joint Strike Fighter (JSF) and the X-38 Spacecraft using a lifting-body concept that will Operate at supersonic/hypersonic Mach numbers, the need for panel flutter analysis has received broad acknowledgement. The linear and nonlinear analysis of the panel flutter has been studied extensive during the past ...
