“…It has been effectively established for the investigation of elastic metamaterial and its accuracy has been verified within the subwavelength range. 23,28 Via effective medium method, the effective mechanical parameters of the metamaterial can be obtained since the lattice constant of the LLR is much smaller than the flexural wavelength of the plate. And the related problem can be greatly simplified when the metamaterial plate considered here is treated as a homogeneous plate with effective mass density.…”

“…Similar work was finished with continuum resonators consisting of rubber and steel attached to a sandwich plate. 22 Meanwhile, STL through a metamaterial plate comprising of shunted piezoelectric patches and a thin plate 23 was increased and its frequency range was broadened by the negative capacitance shunting circuits. Moreover, Collet et al 24 proposed an effective approach to minimize the acoustic radiation of a semi-active metacomposites by optimizing the impedance of the shunted circuit.…”

In the context of sound incident upon a metamaterial plate, explicit formulas for sound transmission loss (STL) are derived in the presence of external mean flow. Metamaterial plate, consisting of homogeneous plate and lateral local resonators (LLRs), is homogenized by using effective medium method to obtain the effective mass density and facilitate the calculation of STL. Results show that (a) vigorously oscillating LLRs lead to higher STL compared with bare plate, (b) increasing Mach number of the external mean flow helps obtain higher STL below the coincidence frequency but decreases STL above the coincidence frequency due to the added mass effect of light fluid loading and aerodynamic damping effect, (c) the coincidence frequency shifts to higher frequency range for the refracted effect of the external mean flow. However, effects of the flow on STL within negative mass density range can be neglected because of the lateral local resonance occurring. Moreover, hysteretic damping from metamaterial can only smooth the transmission curves by lowering higher peaks and filling dips. Effects of incident angles on STL are also examined. It is demonstrated that increasing elevation angle can improve the sound insulation, while the azimuth angle does not.

Em trabalhos recentes, destaca-se a utilização destes circuitos para o controle multimodal (LOSSOUARN; DEÜ; AUCEJO, 2015).…”

“…Esses dois grandes grupos de soluções (metamateriais e materiais inteligentes), para o problema de vibração e ruído em sistemas mecânicos, se consolidam como estado da arte. Contudo, a solução híbrida, os chamados smart metamaterials, apenas recentemente começou a ser explorada para aplicação de controle vibro-acústico (GIORGIO et al, 2015;NOUH;ALDRAIHEM;BAZ, 2016;ZHANG et al, 2015;HU et al, 2016), contemplando-se um novo horizonte de possibilidades para pesquisa e desenvolvimento. Com tal panorama, seria possível utilizar a versatilidade dos elementos piezelétricos no contexto de estruturas periódicas, o que conferiria propriedades únicas a estas soluções híbridas, mais versáteis que cada uma das abordagens individuais.…”

“…Em sua grande maioria, os metamateriais são abordados do ponto de vista passivo, ou seja, o conceito das células unitárias faz uso de suas propriedades de inércia, rigidez e amortecimento, constituindo-se de elementos rígidos (quando se explora espalhamento de Bragg) ou ressonadores (quando se explora efeitos de ressonância local). Em comum, as duas abordagens mencionadas se aproveitam da organização dos insertos arranjados de forma periódica, sendo utilizado o conceito de células unitárias (VAN BELLE et al, 2016;LI;ZHANG;LIU, 2017;RAGHAVAN;PHANI, 2013;BELI et al, 2019).…”

Metamaterials (MMs), which include phononic crystals (PCs) as a particular type, exhibit anomalous wave propagation properties through artificial design of topologies or lattice forms of unit‐cells. Recent advancements in MMs signify an ascendant research trend, providing promising design ideas and means for unprecedented wave propagation properties. The imperative for on‐demand, real‐time active control of wave propagation underscores the significance of tunable manipulation of acoustic/elastic waves, promoting the design and development of tunable MMs. Furthermore, the versatility of intelligent materials and their ongoing development and innovation contribute significantly to the emergence of diverse intelligent MMs. This comprehensive survey provides an overview of recent advancements and current research trends in the interdisciplinary field of intelligent MMs with electro‐/magneto‐mechanical couplings. The primary objective of the review is to emphasize significant progress in agile manipulation of acoustic/elastic waves in electro‐/magneto‐mechanical coupled MMs, followed by an in‐depth exploration of intelligent metasurfaces, topological MMs, non‐Hermitian parity‐time symmetric wave systems, odd elastic MMs, and spatiotemporally modulated MMs. Special emphasis is given to multi‐field coupling effects. The review concludes with a summary and outlines potential prospects, offering a timely and informative guide for future studies on actively tunable PCs and MMs in practical engineering applications.
