Summary: Polyurethane (PU) foams are commonly used in the automotive industry as sound absorbing and cushioning materials. In this study, the effect of expandable polystyrene (EPS) as a filler in PU foams on acoustic property was investigated. It was found that increasing EPS content enhanced the low-frequency sound absorption performance of PU foams by increasing the sound wave propagation path. The removal of EPS using toluene resulted in lower sound absorption performance compared to PU foam with 0 wt% EPS content, confirming the role of EPS in improving sound absorption performance in PU foams.

Summary: The study found that the thermal stability of RPUFs was improved at low percentages of TFFs, but the effect weakened as the content increased. Meanwhile, the thermal insulation performance and acoustic features were also influenced to some extent by TFFs, which can reduce the air permeability of the foam.

Summary: Hybrid composites of polyurethane (PU) matrix and natural kenaf fiber filler were fabricated and optimized using the Response Surface Methodology (RSM) coupled with Central Composite Design (CCD). The acoustic performance of the composites was investigated using the impedance tube method, and the prediction models showed high accuracy. The addition of kenaf fibers significantly improved the acoustic absorption of the pure PU foam, and the optimized composite sample had a 35.4% increase in sound absorption compared to pure PU foam.

Summary: A multilayered graphene oxide-impregnated polyurethane (GO-PU) foam structure is proposed to maximize the sound absorption coefficient (SAC) by controlling the sound absorption properties of each PU layer via GO impregnation. The optimal multilayered structure is derived via theoretical predictions using matrix calculations. The impregnation effect of GO significantly improves the SAC, and the layer arrangement optimization further enhances the average SAC.

Summary: In the field of transportation engineering, wind tunnels remain the best option for analyzing structural vibration and emitted noise. However, due to limitations and discrepancies among wind tunnel facilities, researchers have developed a numerical method called PEDEM to simulate the experimental conditions and study the structural response of panels subjected to turbulent boundary layer excitation.

Summary: This paper presents a method to identify wave equations' parameters using wave dispersion characteristics in two-dimensional domains. The proposed approach minimizes the difference between an analytic formulation of the dispersion relation and wavenumbers calculated from solution fields. The method is tested on various test cases and shows accurate retrieval of wave equation parameters.

Summary: This study focuses on predicting and analyzing dispersion curves of waveguides, which are critical in structural health monitoring. Despite using advanced methods like wave finite element method (WFEM), determining dispersion curves still presents numerical difficulties and long computation time. This paper proposes a metamodeling approach based on kriging theory to overcome these difficulties. Results from numerical simulations show that constructing learning sets for kriging metamodels using WFEM representations is a promising strategy in terms of accuracy and computing time.

Summary: This study investigates the acoustic radiation from a ribbed plate with inner resonance using explicit design rules and a homogenized model for flexural waves. The results show that bending wave propagation differs significantly from classical models in the presence of strong contrast between constituents, resulting in inner resonance. The homogenized model effectively complements the Timoshenko orthotropic plate model and provides valuable insights into the structural response on common vibroacoustic indicators.

Summary: This study focuses on the dynamic modeling of a negative stiffness absorber made up of curved beams, providing design rules based on stiffness and elastic energy stored in the negative stiffness elements. Unlike traditional approaches using equivalent spring-mass system equations, this paper presents a modeling method based on beam dynamics, incorporating the generation of negative stiffness in prestressed Euler beams to predict behavior. The proposed beam model is validated against existing models in literature and finite element simulations. Experimental results from a 3D-printed mock-up confirm the theoretical predictions of the observed softening trend due to axial loading on the curved beams.
