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

This paper proposes a bio-inspired multi-cell corrugated tube for use in energy absorption.
The proposed structure consists of two parts: an inner rib and a corrugated tube into which …

A novel type of tubular structure has been proposed in this paper, which is the first tubular
structure with auxeticity in the wall thickness as well as in the radial direction. This tubular …

Structures with negative Poisson's ratios have been widely applied in existing engineering,
especially in the field of energy absorption. To design double-arrowed auxetic structures to …

In this study, 2D triangular anti-trichiral structures and auxetic stents, under compression,
were introduced. The cores of the anti-trichiral structures were the equilateral triangles. The …

This paper presents an experimental study on impact behaviour and plastic evolution of
chiral structure subjected to in-plane impact loading using a Split Hopkinson pressure bar …

In this study, some new 2D auxetic metamaterials were investigated and called octagonal
auxetic metamaterials. The structures were examined by numerical and experimental …

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

In this paper, the modified SIMP topology optimization (TO) method was used, to introduce
diverse auxetic unit cells with different volume fractions, composing of the symmetric, chiral …

This paper deals with the effect of unit cell configuration on the energy absorption response
of different cellular auxetic structures subjected to quasi-static and dynamic loadings through …
