In practice, it is achieved by means of a local reduction in thickness (axisymmetric pit with a parabolic profile) and the addition of a thin viscoelastic coating in a central region of uniform thickness (plateau). The vibration absorption induced by the ABH, enables the design of stiff, light and non-resonant panels. In this paper, a study of the ABH effect for a sandwich panel made of a honeycomb core and fiberglass skins, which gives rise to both bending and shear effects is conducted. In particular, it is shown that the equations of motion of the thick, symmetrical sandwich panel with variable characteristics is obtained within the framework of the Nilsson’s theory. These equations lead to a sixth-order analytical model that is used to determine the dispersion curves of the sandwich and also to establish an analytical model of the ABH inserted in a sandwich panel. Experimental tests postproceed by two complementary inverse methods are used to characterize the sandwich’s mechanical properties. In particular, the model powered by experimentally determined parameters is used to analyze the effect of shear on the ABH effect, and to demonstrate that shear-induced softening is beneficial to ABH-induced absorption.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"604 ","pages":"Article 118991"},"PeriodicalIF":4.3,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143387941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering an array of scattering elements, a model had been proposed that generated an angular dependent band gap to locate the incoming echo. However, the jaw function at lower frequencies (4 – 20 kHz), is not clear, although it might aid in the acoustic localisation of signature whistles from conspecifics. Herein, an underwater test on a bottlenose dolphin jawbone filled with paraffin wax (density similar to acoustic fats) showed frequency responses shifting in spectral peaks as a function of the incoming signal angle at whistle fundamental frequencies. These spectral responses were found similar to those of an in air acoustic metamaterial leaky wave antenna for which signature whistles were presented.

Based on those symmetry groups, we introduce families of designs that are straightforward to replicate. By exploring the coupling between Bragg scattering and local resonance mechanisms through a comprehensive parametric study, we demonstrate the feasibility of achieving extremely wide, complete omnidirectional BGs in single-phase PnCs. Numerical simulations and experimental results confirm the presence of strongly coupled BGs with superior attenuation properties for both P- and S-waves, particularly in designs with large resonators and thin connectors. We reveal an extremely wide 118% complete omnidirectional BG with remarkable attenuation of up to 80 dB after 3 rows of unit cells. Our study shows that the specific arrangement of connectors and resonators within the PnCs, analogous to masses and springs, plays a crucial role in the formation of strongly coupled resonant-Bragg BGs. Furthermore, the study challenges the conventional emphasis on symmetry in PnC design, suggesting that less sophisticated symmorphic designs can achieve comparable BG performance to their nonsymmorphic counterparts. This work contributes to the understanding of BG formation mechanisms in single-phase PnCs and offers guidelines for engineering enhanced vibration isolating devices.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"603 ","pages":"Article 118973"},"PeriodicalIF":4.3,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143232659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The absolute nodal coordinate formulation (ANCF) is widely used in the dynamic modeling and analysis of cable structures due to its advantages of accurately and effectively dealing with large deformation problems.

Therefore, this paper innovatively derives a coupled integration algorithm for solving the DAEs—GC-α method. This algorithm is conceived along the principle of GC coupled integration algorithm, and the generalized α method with numerical damping is introduced to ensure the stability of the algorithm and reduce the adverse effects of high-frequency components in the vibration of cable structures.

Especially when signals are related to microleakage or seepage, the resulting amplitude reduction, frequency ambiguity and waveform distortion seriously affect the monitoring sensitivity and accuracy. In response to the above challenges, this paper proposes a feasible framework including Fractional domain adaptive noise cancellation, signal enhancement and multi-scale feature extraction to achieve pipeline weld crack leakage monitoring under strong background noise and low leakage rate. Firstly, the optimal separation mode of leakage signal and noise signal is found by fractional Fourier transform. On this basis, fast local Laplace filtering enhances the wavelet time-frequency diagram to improve the characterisation ability of microleakage signal features. Then, a multi-scale convolutional network with dimension-aware attention is carefully designed to extract microleakage features accurately. Finally, the superiority and effectiveness of the proposed framework are verified by carefully designed pipeline weld crack leakage experiments with three different morphologies of circumferential, axial and curvilinear directions with equal leakage area. Compared with other advanced methods, the recognition accuracy of the proposed framework for different microleakage conditions under strong background noise is as high as 98.22%. In addition, the ablation experiment illustrates the necessity of the proposed module for efficient channel dimensional information interaction and lightweight model parameters.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"604 ","pages":"Article 118980"},"PeriodicalIF":4.3,"publicationDate":"2025-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143097002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
