Materials with negative Poisson's ratio attract considerable attention due to their underlying
intriguing physical properties and numerous promising applications, particularly in stringent …

This is a review on the emergent field of topological mechanics, where concepts from
electronic topological states of matter are applied to mechanics. We focus on the …

New and innovative lightweight materials are the key demands of the automotive and
aerospace industry. Exceptional energy absorption properties can be obtained from designs …

Auxetic materials exhibiting a negative Poisson's ratio are shown to have better indentation
resistance, impact shielding capability, and enhanced toughness. Here, we report a class of …

Auxetic materials become thicker rather than thinner when stretched, exhibiting an unusual
negative Poisson's ratio well suited for designing shape transforming metamaterials. Current …

Metamaterials with artificially designed architectures are increasingly considered as new
paradigmatic material systems with unusual physical properties. Here, we report a class of …

Auxetic mechanical metamaterials are artificially architected materials that possess negative
Poisson's ratio, demonstrating transversal contracting deformation under external vertical …

The auxetic foams composed of highly porous thermoplastic polyurethane (TPU) exhibit an
attractive behaviour of withstanding a large volume reduction upon the cyclic compressive …

Elastic instability has been increasingly used to design buckling-induced auxetic
metamaterials. However, only limited patterns of existing three dimensional (3D) buckling …

Most conventional materials expand in transverse directions when they are compressed
uniaxially resulting in the familiar positive Poisson's ratio. Here we develop a new class of …
