A literature review for the analysis of structured and unstructured uncertainty effects on vibroacoustic.
Résumé
A better knowledge of the structural response of periodic structures can be achieved through the classification of possible uncertainty, to be included in the predictive models. Nowadays, the wave finite element approach is used for the simulation of periodic structures to reduce the computational cost. On the contrary, it introduces a higher complexity in the model formulation. Recently, the spectral approach has shown its relevance in the uncertainty analysis of structures. This paper presents the literature on uncertainty effect on vibroacoustic of periodic media. The present work is an initial literature study on available analytical and numerical approaches for capturing the parametric and non-parametric uncertainties.
