... Abstract Meta-materials are artificial materials that perform superior properties in addition to natural behavior. Regardless of their chemical properties, metamaterials show high performance due to their geometric orientation. There are mechanical metamaterials that are used in vibration...

... Abstract Naturally available materials are inadequate in many advanced applications, including space. Therefore, functional materials answer the requirement of operation-specific customized characteristics. Soft matter-based metamaterials exhibit various desired physical properties for space...

... Abstract A dual-purpose metamaterial structure that can concurrently suppress vibrations and scavenge energy is presented. The metamaterial assembly presented in this work uses a permanent magnet-coil system in addition to an elastic cantilever beam to perform its dual functions. A prototype...

... a rectangular array of unit cells sitting in an aluminum plate. Each unit cell is comprised of a shape memory alloy substrate and a lead stub. The controllable bandgap of such a metamaterial system can be achieved due to the stiffness change of nitinol between its martensite phase and austenite phase under...

... detection and localization of the damage sites. In this study, a type of metamaterial ultrasonic radar is proposed for the steerable unidirectional wave manipulation. It contains a circular array of unit cells stuck in an aluminum plate which are delicately arranged in a circular fashion. Each unit cell...

... Abstract Membrane-based acoustic metamaterials have been reported to achieve 100% absorption, the acoustic analogue of photonic black-hole. However, the bandwidth is usually very narrow around some local resonance frequency, which limits its practical use. To address this limitation and achieve...

... Abstract In this study, a kind of elastic metamaterial substructure was designed for the selective mode filtering and transmission of symmetric and antisymmetric elastic waves. It is composed of double-sided aluminum-lead composite cylinders arranged in a periodic pattern bounded on an aluminum...

... Abstract This paper presents a novel shape memory metamaterial, which can achieve adaptively tunable bandgaps for ultra-wide frequency spectrum vibration control. The microstructure is composed of a Shape Memory Alloy (SMA) wire and a metallic spring combined together with bakelite blocks...

... Abstract A novel auxetic metamaterial which is organized in the lattice is presented in this paper. Dynamic uniaxial impact behavior of the auxetic lattice using experiment and finite element simulation is investigated. The corresponding results have proved that the plastic beam-based finite...

... Non-singular transformation is developed to achieve approximate acoustic and elastic cloaking. In the literature, perfect cloaking is realized under the condition of mapping cloak inner boundary to a single point, which gives rise to the development of unconventional metamaterials. Such cloaks...
