Different from conventional materials, materials with negative Poisson's ratios expand
laterally when stretched longitudinally. Known as 'auxetic'materials, the effect means they …

This broad review summarizes recent advances and “hot” research topics in nanophononics
and elastic, acoustic, and mechanical metamaterials based on results presented by the …

An auxetic metamaterial composed of novel re-entrant unit cells was proposed. The new re-
entrant structure was constructed by adding wedge-shaped parts to the conventional re …

In the past decades, auxetic metamaterials have attracted extensive attention due to their
desirable properties. In order to further improve the energy absorption properties of auxetic …

This paper designs a novel reusable gradient negative stiffness (GNS) honeycomb structure
and focuses on investigating its energy absorption (EA). Contrary to classical normal …

Auxetic mechanical metamaterials are artificially architected materials that possess negative
Poisson's ratio, demonstrating transversal contracting deformation under external vertical …

Mechanical metamaterials have been attracting increasing attention for a wide range of
industrial applications, such as energy storage, biomedical, sensors, robotics, etc., owing to …

The 3D auxetic buckling pattern in the compression process is used to design auxetic
structures. However, obtaining this pattern is time consuming and unintentional. In this …

In this paper, the mechanical behavior of bio-inspired nacre-like staggered composites is
studied. The bio-inspired materials, combining stiff and soft constituents, exhibit superior …

As a subcategory of acoustic metamaterials, membrane acoustic metamaterials (MAMs) are
lighter and more adjustable than other types of acoustic metamaterials when it comes to low …
