TL;DR: A method is presented by which the wavenumbers for a one-dimensional waveguide can be predicted from a finite element (FE) model, which involves postprocessing a conventional, but low order, FE model, the mass and stiffness matrices of which are typically found using a conventional FE package.

TL;DR: In this paper, the authors present a review of component mode synthesis (CMS) for the analysis of the dynamics of uncertain structures with non-deterministic properties, and the application of perturbational techniques is considered.

TL;DR: In this paper, the modeling of spatial variations using random fields and the implementation within existing finite element models is presented, which can drastically reduce numerical costs, and the application of the line-sampling technique to estimate the distribution and statistics of eigenfrequencies is presented.

TL;DR: This paper concerns the case where experimental measurements of free-interface modal properties are taken to quantify uncertainty of various components and this data is then used in fixed-interface analysis for the prediction of response statistics.
