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.

Structural-acoustic modeling of automotive vehicles in presence of uncertainties and experimental identification and validation.
TL;DR: This research develops an experimental database devoted to structural vibrations and internal acoustic pressures that is used to perform the experimental identification of the probability model parameters and to validate the stochastic computational model.

Response variance prediction for uncertain vibro-acoustic systems using a hybrid deterministic-statistical method.
Robin S. Langley,Vincent Cotoni +1 more
TL;DR: The method employs a nonparametric model of uncertainty, in the sense that the statistical components are taken to carry diffuse wave fields, and this obviates the requirement for a detailed description of the system uncertainties.

Dynamical energy analysis—Determining wave energy distributions in vibro-acoustical structures in the high-frequency regime
TL;DR: In this article, the authors proposed a new approach for determining the distribution of mechanical and acoustic wave energy in complex built-up structures by interpolating between standard statistical energy analysis (SEA) and full ray tracing.

Wave chaos in acoustics and elasticity
Gregor Tanner,Niels Søndergaard +1 more
TL;DR: In this paper, the authors provide an overview over basic concepts in this emerging field of wave chaos, which ranges from ray approximations of the Green function to periodic orbit trace formulae and random matrix theory and summarizes the state of the art in applying these ideas in acoustics.

Statistical Energy Analysis of Dynamical Systems: Theory and Applications
TL;DR: The statistical energy analysis (SEA) method as discussed by the authors is a general framework of methods rather than a particular technique for the analysis of mechanical vibrations. And it has been used extensively in the design of aircraft, spacecraft launch vehicles, ships, and similar structures.

On the reciprocity relationship between direct field radiation and diffuse reverberant loading.
PJ Shorter,Robin S. Langley +1 more
TL;DR: It is shown that the existing diffuse-field reciprocity relationship can be extended to encompass connections that possess an arbitrary number of degrees of freedom.
Journal ArticleDOI
Statistical energy analysis: a critical overview
TL;DR: In this paper, the authors present a discussion of the rationale for the use of probabilistic energetic models for high-frequency vibration prediction, and introduce the postulate upon which conventional SEA is based.

Finite Elements: Their Design and Performance
TL;DR: In this paper, MacNeal examines why finite elements sometimes fail and how element designers have corrected their failures and provides quantitative analyses of failure modes and illustrations of possible side effects found in proposed remedies, providing a practical understanding of finite element performance.
