Auxetic foams counter-intuitively expand (shrink) under stretching (compression). These
foams can exhibit superior mechanical properties such as resistance to shear and …

Auxetic materials and structures have attracted increasing attention because of their
extraordinary mechanical properties. Various types of auxetic tubular structures have been …

Auxetic materials are a class of mechanical metamaterials. They exhibit lateral expansion
under tension, and lateral contraction under compression. Such metamaterials have …

Inspired by sonic engineering, locally resonant metamaterials have attracted much attention
from researchers in civil engineering for their unique characteristics of stress wave …

As a branch of auxetics, the re-entrant hexagonal honeycomb has many superior
mechanical performances. However, most research focused on two-dimensional (2D) re …

Auxetics are a class of structural metamaterials with a negative Poisson's ratio. In
comparison to conventional structures, auxetic structures are proven to exhibit several …

Additive manufacturing is rapidly evolving and opening new possibilities for many industries.
This article gives an overview of the current status of additive manufacturing with polymers …

In this study, the mechanical properties of a vertex-based hierarchical re-entrant honeycomb
structure (H v) were investigated. Firstly, the overlapping effect of struts was considered in …

Missing rib auxetics with a reinforced central core may have tunable negative Poisson's
ratios (NPRs) and other mechanical parameters. In analogy with the other enhanced …

As typical mechanical metamaterials with negative Poisson's ratios, auxetic metamaterials
exhibit counterintuitive auxetic behaviors that are highly dependent on their geometric …
