For the periodic structures, it will be of great value the classification of the uncertainties to be included in the predictive models. The aim of such definition must be related to the identification of the location, level and nature of imperfections and also their effects on the vibroacoustic response. It is expected to understand how the aleatoric and epistemic uncertainties can be possibly managed in the same models. Models do exist for the analysis of both aleatoric and epistemic uncertainties, but the actual aim is to evaluate their incorporation into the analysis of the ‘cell,’ which can be done nowadays with wave finite element method or spectral methods. Another point should be to assess if the simulation of the degree of uncertainty should require the simulation of a single cell, numerically interrogated in a cycle, or the simulation of a number of cells in which the uncertainty propagates. The final goal will be to define the robustness of the models concerning some engineering parameters (for example related to tolerance and uncertainties associated with manufacturing at different scales) when these latters are properly bounded. All the tools, which can provide a further insight of this subtle topic, will be foreseen at analytical, numerical and experimental levels I am interested in the project because of the study of Uncertainty Quantification interest to me. In reality, the uncertainty and variability raise many issues concerning safety, reliability, quality of performance, worst-case behavior and-and many more of the final product. This issue created a demand for developing modeling methods which include uncertainties in the model, input parameter, and properties of the structure, which results into more reliable structural performance.
