Polyurethane (PU) foams, valued for their low density and cost-effectiveness, face mechanical limitations, prompting nanoparticle reinforcement. This study investigates, for the first time, the buckling and vibration properties of PU matrices reinforced with multi-walled carbon nanotubes (MWCNTs), GNPs, and their hybrid combinations. This hybrid composite plate integrates two layers of piezoelectric sensors and actuators. The dynamics behavior of the system is modeled using linear three-dimensional piezo-elasticity theory. Through dual transformation pairs, the equations are converted into two decoupled, lower-order spatial state-space systems that describe both the plate's planar and transverse mechanical behaviors. Additionally, various parametric studies are conducted for the first time to explore the impacts of different ratios of MWCNT:GNP, different flake sizes of GNP, MWCNT aspect ratios, weight fractions of nanofillers, reinforced patterns, dimension ratios of the plate, electrical boundary conditions, and various boundary conditions for the edge of the plate on the natural frequency and buckling properties of hybrid smart composites. The results show that natural frequency and buckling load in PU nanocomposites rise with nanofiller weight fraction, peaking with FG-GNP24 at 1.0 wt% featuring 3.5 % and 6.2 % gains for frequency and buckling, respectively. Hybrid MWCNT-GNP systems excel at specific ratios: 5:1 (MWCNT-GNP1.5) surpasses single fillers, while 1:1 (MWCNT-GNP5) performs best at 0.25–0.5 wt%. Open-circuit piezoelectric configurations outperform closed-circuit. X-O nanofiller patterns optimize frequency in MWCNT-GNP24 composites (8:2, 5:1 ratios), while uniform distributions maximize buckling resistance.</div></div>","PeriodicalId":49367,"journal":{"name":"Wave Motion","volume":"137 ","pages":"Article 103543"},"PeriodicalIF":2.1,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, a stronger next-neighbor coupling significantly enhances the amplitude of modulation instability, confirming that the nonlinear electrical lattice supports localized nonlinear waves. Analytical analysis, considering the self-phase modulation parameter, reveals the existence of three types of coupled soliton modes: bright-bright solitons, dark-bright solitons, and bright-dark solitons, influenced by the nearest neighbor coupling. Numerical simulations further illustrate the development of modulation instability through modulated wave patterns.

Discrete lumped-mass models and discrete distributed-mass finite element models are both generally used to analyze LRMMs. While the former is accurate only near the fundamental resonance frequency of resonators, the latter’s accuracy is tightly coupled to the computational cost. In this study, an analytical procedure based on the spectral element method (SEM) is proposed to analyze both undamped and damped LRMMs as continuous systems. We compare LRMMs’ band structures to those obtained by discrete models and show that the proposed procedure is capable of capturing the wave dynamics of these materials very accurately and with negligible computational cost. The behavior of a finite LRMM waveguide is also studied through displacement transmissibility. In addition to the attenuation provided by band gaps, we investigate the effects of constant viscous damping and frequency-dependent viscoelastic damping, which proved to be a straightforward extension of the undamped spectral element model.</div></div>","PeriodicalId":49367,"journal":{"name":"Wave Motion","volume":"136 ","pages":"Article 103527"},"PeriodicalIF":2.1,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143510176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing research has focused mainly on periodic metamaterial structures with identical vibration absorbers or resonators, while metamaterial structures with non-uniform and aperiodic resonators have received little attention. This paper presents a method for constructing broad frequency bands of low-vibration transmission using tailored resonators without enforcing restrictions on the resonators’ dynamic properties and positions. In contrast to conventional periodic metamaterials, the method we present connects individual localised resonance bands by strategically tuning and customising the resonators’ dynamic properties. We demonstrate through comparative case studies that tailored resonators can achieve broader attenuation bands with less total mass than periodic and identical resonators. Furthermore, we show that the number of resonators to achieve a preset vibration transmission level can be minimised using an iterative analysis process. Our approach provides enhanced design flexibility and efficiency in creating broad attenuation bands, offering new possibilities for practical vibration control applications where traditional periodic metamaterials face limitations.</div></div>","PeriodicalId":49367,"journal":{"name":"Wave Motion","volume":"136 ","pages":"Article 103528"},"PeriodicalIF":2.1,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143510177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
