Mechanical metamaterials can be defined as a class of architected materials that exhibit
unprecedented mechanical properties derived from designed artificial architectures rather …

Structural metamaterials presenting negative values of one or more mechanical and
thermomechanical indices–namely the Poisson's ratio, the linear compressibility, and the …

Due to the excellent energy absorption performance of re-entrant hexagonal honeycomb
(RHH) with negative Poisson's ratio (NPR) property, an improved Diabolo shaped …

Traditional auxetic metamaterials are characterized by negative Poisson's ratio but weak
stiffness. In this paper, a new auxetic metamaterial, re-entrant star-shape anti-chiral auxetic …

This work proposes a novel metamaterial incorporating the auxeticity and thermal shrinkage
by originally introducing a bi-material double-square into the star-shaped configuration. The …

In recent studies, some structures with alternating positive and negative Poisson's ratio have
been proposed, which provides a new direction for structural design. The novelty of this …

As an emerging field, mechanical metamaterials have brought new options for energy
absorption. Herein, the corrugated wall mechanical metamaterial with unique deformation …

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 …

In this study, a three-dimensional compression-torsion coupled negative Poisson structure
was designed by combining the perforated plate with the inclined rod out of the plane. This …

Multistable mechanical metamaterials are periodic structures whose unit cells show bistable
configurations. The snap-through behavior of the unit cell enhances the energy dissipation …
