Analytical frequency response solution for composite plates embedding viscoelastic layers
TL;DR: In this paper, analytical damped free-vibration and frequency response solutions are obtained for the analysis of composite plates structures embedding viscoelastic layers on the basis of the principle of virtual displacement, layer-wise models related to linear up to fourth order variations of the unknown variables in the thickness direction are treated.

Numerical modelling of vibro-acoustic problem in presence of uncertainty: Application to a vehicle cabin
TL;DR: In this article, the Generalized Polynomial Chaos (gPC) method is applied to a vehicle to investigate the sound pressure level inside the cabin, and the results show that the gPC method is more efficient compared to the direct Monte Carlo simulation (MC) without causing significant loss of accuracy.

A complex plane analysis of α‐dispersions in some polymer systems
S. Havriliak,S. Negami +1 more
TL;DR: In this paper, the authors measured and analyzed the complex dielectric behavior of the α-dispersions for five polymers [i.e., polycarbonate and polyisophthalate esters of bisphenol A, isotactic poly-(methyl methacrylate), poly(methyl acrylate) and a copolymer of phenyl methacellitrile] and found that the usual methods of analysis cannot be used to represent the data.
