Humans are sensitive to air-borne sound as well mechanical vibrations propagating in solids the frequency range below 20 kHz. Therefore, development of multifunctional filters for both vibration reduction and insulation within human sensitivity is a research topic primary interest. In this paper, high-contrast biphasic metamaterial, composed periodic elastic solid cells with air-filled voids, presented. By opening intercellular air-communicating channels introducing channel-bridging solid-solid couplings, dispersion spectrum metamaterial can be modified achieve complete large bandgaps acoustic waves. From methodological viewpoint, eigenproblem governing free wave propagation solved using hybrid analytical-computational technique, while waveform classification based on polarization factors expressing fraction kinetic energies stored fluid phases. Based these theoretical results, metafilter consisting an array finite number conceived provide technical solution engineering applications. The forced response virtually tested computational framework assess its performance passively controlling broadband signals environments. Quantitative results synthesized by transmission coefficients demonstrate that remarkably reduce transmitted band sensitivity.

Mechanical metamaterials exhibit several unusual mechanical properties, such as a negative Poisson's ratio, which impart additional capabilities to materials. Recently, hydrogels have emerged exceptional candidates for fabricating that offer enhanced functionality and expanded applications due their unique responsive characteristics. However, the adaptability of these remains constrained underutilized, they lack integration hydrogels' soft characteristics with metamaterial design. Here, we propose structurally transformable reconfigurable hydrogel-based through three-dimensional (3D) printing lattice structures composed multishape-memory poly(acrylic acid)-chitosan hydrogels. By incorporating reversible shape-memory mechanisms control structural arrangements lattice, can under various environmental conditions, including auxetic behavior, ratios switchable from zero or positive. These adaptable responses across different states arise changes in surpassing gradual observed conventional stimuli-responsive The application multimode biomedical stents demonstrates practical settings, allowing them transition between expandable, nonexpandable, shrinkable states, corresponding ratios. integrating materials design, significantly enhance functionality, advancing development smart biomaterials.

A novel 316L stainless steel Vertex Modified BCC (VM-BCC) lattice unit cell with attractive performance characteristics is developed. Lattice structure, as well the sandwich panel, are constructed. Numerical simulation utilized to simulate quasi-static compression, dynamic compression and blast behavior considering rate-dependent properties, elastoplastic response nonlinear contact. Finite element results validated by comparing experimental results. Parametric studies conducted gain insight into effects of loading velocity, equivalent TNT load explosion distance on pattern panel. Testing indicate that proposed VM-BCC structure exhibits more superior plateau stress specific energy absorption (SEA) than those or Octet one. The will provide reference for improving protective efficiency in key equipment fields enhancing overall safety.

Abstract Auxetic metamaterials refer to materials and structures with extraordinary deformation, i.e., transverse expansion (contraction) under uniaxial tension (compression). In recent decades, a very wide range of innovative functional performance has been discovered stemming from this behavior. This desirable exhibition adaptivity, programmability, functionality provides great potential in soft intelligent systems. However, thus far, the mainstream research on auxetic focused subjective design, monotonic mechanical properties, passive tunability. review thorough overview classical properties applications, primary objective proposing new roadmap auxetics for advances interdisciplinary field. The fundamental works are categorized different configurations mechanisms. particular, integration shape morphing, actuation, sensing, multiphysical response, inverse design is reviewed detail. To accelerate development smart structural systems, applications generalized into robotics (outside body), human–machine interaction (surrounding healthcare devices (inside body). Finally, several significant topics emphasized theory, material choice, manufacturing technique, applications.
