...K. Zhou; J. Tang Mode shape information plays the essential role in deciding the spatial pattern of vibratory response of a structure. The uncertainty quantification of mode shape, i.e., predicting mode shape variation when the structure is subjected to uncertainty, can provide guidance for robust...

...Biswarup Bhattacharyya; Eric Jacquelin; Denis Brizard A proper orthogonal decomposition (POD)-based polynomial chaos expansion (PCE) is utilized in this article for the uncertainty quantification (UQ) of an impact dynamic oscillator. The time-dependent nonsmooth behavior and the uncertainties...

... multiple response Gaussian process Bayesian inference uncertainty quantification The characterization of dynamic properties of structures is the foundation for response analysis, system/fault identification, and control, where frequency response functions (FRFs) are commonly used to facilitate...
