Asymmetric chiral and antichiral mechanical metamaterials with tunable Poisson’s ratio

Mechanical metamaterials with zero or negative Poisson’s ratio were subject to increasing research interest over the last few years. Their energy absorption capabilities make them suitable for impact

On the application of additive manufacturing methods for auxetic structures: a review

TLDR
In this study, a detailed discussion of the various AM techniques used in the fabrication of auxetic structures is presented to provide an in-depth understanding of the current level of research and gauge the vitality of such manufacturing as a production method.

Auxetic Metamaterials for Biomedical Devices: Current Situation, Main Challenges, and Research Trends

Auxetic metamaterials are characterized by a negative Poisson ratio (NPR) and display an unexpected property of lateral expansion when stretched and densification when compressed. Auxetic properties

Modeling and Analysis of Structures with Negative Poisson's Ratio

Auxetic structures are the structures with negative poisons ratio and display the peculiar behaviour of lateral expansion when they are stretched which is different from conventional structures. They
