Numerical and experimental validation of a hybrid finite element-statistical energy analysis method
TL;DR: The theory behind the hybrid method combining FE and SEA for predicting the steady-state response of vibro-acoustic systems with uncertain properties is summarized and a number of detailed numerical and experimental validation examples for structure-borne noise transmission are presented.

On the use of the asymptotic scaled modal analysis for time-harmonic structural analysis and for the prediction of coupling loss factors for similar systems
Sergio De Rosa,Francesco Franco +1 more
TL;DR: In this article, the authors present the results of an ongoing research on a scaling procedure aimed at the reduction of the computational cost associated, in a deterministic approach, to the wavelength simulation.

Estimation and veering analysis of nonlinear resonant frequencies of cracked plates
TL;DR: In this paper, the nonlinear vibration response near loci veerings and crossings due to the variation of crack length is investigated in detail, and a novel method for estimating the resonant frequency is introduced by generalizing the concept of bilinear frequency approximation, and the method is validated with the results of nonlinear forced response analysis for several veering regions.

Multilevel model reduction for uncertainty quantification in computational structural dynamics
TL;DR: This work deals with an extension of the reducedorder models (ROMs) that are classically constructed by modal analysis in linear structural dynamics for which the computational models are assumed to be uncertain.

Numerical determination of statistical energy analysis parameters of directly coupled composite plates using a modal-based approach
TL;DR: In this paper, the modal information of composite plates is statistically evaluated by the discrete singular convolution method with random boundary conditions, and the proposed methodology not only provides an efficient use of SEA method in high frequency vibration analysis of composite structures, but also enhances SEA accuracy in mid frequency region in which conventional SEA fails.

TL;DR: The finite element method for the algebraic Eigenvalue problem of distributed-parameter systems was introduced in this article. But it is not suitable for the linear system theory of single-degree-of-freedom (SDF) systems.
