Materials and structures with negative Poisson's ratio exhibit a counter-intuitive behaviour.
Under uniaxial compression (tension), these materials and structures contract (expand) …

With the proliferation of flexible displays and the advances in smart materials, it is now
possible to create interactive devices that are not only flexible but can reconfigure into any …

The term “mechanical metamaterials” encompasses a wide range of systems whose
anomalous mechanical properties arise primarily from their structure rather than …

In recent years, 3D structures with negative Poisson's ratio (auxetic) have attracted great
interest. Many polymer and metal 3D auxetic structures have been manufactured using …

Background Among additive manufacturing techniques, the filament-based technique
involves what is referred to as fused deposition modeling (FDM). FDM materials are …

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 …

The homogenization of periodic hexachiral and tetrachiral honeycombs is dealt with two
different techniques. The first is based on a micropolar homogenization. The second …

Auxetic and other mechanical metamaterials are typically studied in situations where they
are subjected solely to mechanical forces or displacements even though they may be …

Rational design of artificial microstructured metamaterials with advanced mechanical and
physical properties that are not accessible in nature materials is very important. Making use …

A novel class of transversely-isotropic metamaterials with the potential to exhibit a wide
range of Poisson's ratios and stiffnesses is proposed in this work. These metamaterials …
