Herein, the fundamental scientific theories behind this class of novel metamaterials, along with their fabrication techniques and potential engineering applications beyond mechanics are reviewed. Explored examples include the recent progresses for both mechanical and functional applications. Finally, the current...
Metamaterials are rationally structured composites, made of periodically or aperiodically organized building blocks, that manifest extreme properties and exotic functionalities that go beyond constitutive bulk materials1. Owing to the unprecedented possibilities enabled by metamaterials, the past decade has witne...
Low-density, high-strength, ductile metal mechanical metamaterials are in high demand for engineering applications but remain out of reach by the Gibson-Ashby model. Here, we demonstrate a new design concept based on a generalized theoretical model or an extended Gibson-Ashby model to overcome ...
Suitably engineered mechanical metamaterials show static non-reciprocity—that is, the transmission of motion from one side to the other depends on the direction of that motion. When an object is pushed on one side and the opposite side moves by a certai
“We created soft, mechanicalmetamaterialswith flexible, conductive polymer networks that can compute all digital logic computations,” said Ryan Harne, James F. Will Career Development Associate Professor, Penn State. “Our paper reports a way to create decision-making functionality in ...
61Altmetric Metrics Abstract Mechanical metamaterials exhibit properties and functionalities that cannot be realized in conventional materials. Originally, the field focused on achieving unusual (zero or negative) values for familiar mechanical parameters, such as density, Poisson's ratio or compressibility,...
Mechanical metamaterials are engineered materials whose structures give them novel mechanical properties, including negative Poisson’s ratios, negative compressibilities and phononic bandgaps. Of particular interest are systems near the point of mechani
Mechanical energy metamaterials have been proposed as a promising technology integrated multiscale architected structures with energy materials, which have opened an exciting venue for energy harvesting under extreme conditions such as the cosmic environment. Mechanical energy metamaterials are envisioned as ...
Molecular dynamics simulations were performed on nanostructured metamaterials (NMs) with gyroid, diamond, and primitive structures to evaluate their mechanical behavior, especially elastic properties. Unlike the constant nature of Young’s (E) and shear
Starting with applied research, this paper summarizes the theoretical and application research status of metamaterials in ship engineering over the past ten years, focusing on such aspects of mechanical metamaterials and acoustic metamaterials (AMMs)as their lightweight, vibration and noise reduction, and...
