The research field of auxetics, materials or structures exhibiting a negative Poisson's ratio,
has received attention because of the unusually advantageous material properties that can …

This review serves as a comprehensive design strategy for designing quasi-zero stiffness
(QZS) mechanical metamaterials (MMs). It discusses their underlying deformation …

This paper presents for the first time two types of metamaterials based on the fragmentation–
reconstitution of rotating units in order to produce Poisson's ratio discontinuity at the original …

In this paper, a new composite metamaterial structure with negative effective mass density,
negative effective modulus, and an ultralarge Poisson's ratio is designed for vibration …

In this paper, a novel auxetic structure with rotating squares with holes is investigated. The
unit cell of the structure consists of four units in the shape of a square with cut corners and …

In this paper, a new design of auxetic honeycomb is proposed for mechanical performance
enhancement by combining the arc-shaped wall and the normal double-arrowed auxetic …

Auxetic mechanical metamaterials show significant potential to impact many engineering
fields and have been a topic of considerable research interest in recent years. Existing …

In this work, the 3D circular curve transversal-isotropic auxetic structure (3D-CCTAS) is
designed based on a six-fold rotation symmetry in space and combines circular-curve and re …

Auxetic materials are those that exhibit negative Poisson's ratios. Such a unique property
was shown to improve the indentation and impact resistances. Angle-ply composite …

This paper explores a new anisotropic auxetic system that consists of rotating rhombi and
right triangles by inspiration from tangram pieces. The Poisson's ratio was developed by …
