Auxetic structures are a special class of structural components that exhibit a negative
Poisson's ratio (NPR) because of their constituent materials, internal microstructure, or …

Abstract Conventional two-dimensional (2D) re-entrant auxetic honeycomb is one of the
earliest examples of auxetic metamaterials. Recently, plenty of 2D re-entrant honeycomb …

Auextic materials possessing negative Poisson's ratios have gained great research interest
by virtue of its various exotic mechanical properties while most of these metamaterials rely …

Honeycombs derived from the combination of multiple kinds of structures have better energy
absorption compared with a single structure. A novel bidirectional re-entrant honeycomb …

An auxetic metamaterial is a type of mechanical metamaterial that has a negative Poisson's
ratio. Most auxetic metamaterials are truss-based or originate from Boolean operations of …

Auxetic materials have garnered significant attention due to their lightweight and excellent
energy absorption capabilities. Nonetheless, they often display relatively lower stiffness …

In this study, four novel three-dimensional (3D) warp and woof structures with negative
Poisson's ratio (NPR) were designed and assembled using the interlocking assembly …

The effectiveness of sandwich structure with auxetic 3D re-entrant lattice core and semi-
auxetic braided composite face sheets subjected to high-velocity impact have been …

This work proposes a new auxetic lattice based on replacing the vertexes of traditional three-
dimensional re-entrant structural with self-similar configurations. Derived by Castigliano's …
