Abstract: Mistuning phenomena exist in the bladed disk due to the inevitable deviations among blades' properties, e.g., stiffness, mass, geometry, etc., leading to localization and response amplification. The dynamic performance of ...

Abstract: In this paper, a novel and efficient modal analysis method is raised to work on blisk structures based on mixed-dimension finite element model (MDFEM). The blade and the disk are modeled separately. The blade model is ...

Abstract: This research concerns the uncertainty analysis and quantification of the vibration system utilizing the frequency response function (FRF) representation with statistical metamodeling. Different from previous statistical ...

Abstract: Pretension is utilized by large space structures such as deployable mesh reflector antennas and flexible solar cell wings to maintain forms and stiffness. Geometric nonlinearity must be taken into account in finite element ...
