Spatio‐Selective Reconfiguration of Mechanical Metamaterials Through the Use of Dynamic Covalent Chemistries [PDF]
Advanced ScienceMechanical metamaterials achieve unprecedented mechanical properties through their periodically interconnected unit cell structure. However, their geometrical design and resulting mechanical properties are typically fixed during fabrication.

Controllable inverse design of auxetic metamaterials using deep learning
Materials & Design, 2021 As typical mechanical metamaterials with negative Poisson’s ratios, auxetic metamaterials exhibit counterintuitive auxetic behaviors that are highly dependent on their geometric arrangements.

Geometric construction of auxetic metamaterials [PDF]
Computer Graphics Forum, 2021 AbstractThis paper is devoted to a category of metamaterials called auxetics, identified by their negative Poisson's ratio. Our work consists in exploring geometrical strategies to generate irregular auxetic structures. More precisely we seek to reduce the Poisson's ratio ν, by pruning an irregular network based solely on geometric criteria.

Auxetic mechanical metamaterials: from soft to stiff
International Journal of Extreme Manufacturing, 2023 Auxetic mechanical metamaterials are artificially architected materials that possess negative Poisson’s ratio, demonstrating transversal contracting deformation under external vertical compression loading.

Hierarchical Auxetic Mechanical Metamaterials [PDF]
Scientific Reports, 2015 AbstractAuxetic mechanical metamaterials are engineered systems that exhibit the unusual macroscopic property of a negative Poisson's ratio due to sub-unit structure rather than chemical composition. Although their unique behaviour makes them superior to conventional materials in many practical applications, they are limited in availability.

Machine learning accelerated design of auxetic structures
Materials & Design, 2023 Auxetic metamaterials exhibit unusual expansion perpendicular to the direction of tensile loading, a behavior known as negative Poisson's ratio (NPR). The microstructures of auxetic metamaterials require rational design.

Non-Auxetic Mechanical Metamaterials [PDF]
Materials, 2019 The concept of “mechanical metamaterials” has become increasingly popular, since their macro-scale characteristics can be designed to exhibit unusual combinations of mechanical properties on the micro-scale. The advances in additive manufacturing (AM, three-dimensional printing) techniques have boosted the fabrication of these mechanical metamaterials ...

Efficient Poisson’s Ratio Evaluation of Weft-Knitted Auxetic Metamaterials
Textiles, 2023 Auxetic metamaterials expand transversely when stretched longitudinally or contract transversely when compressed, resulting in a negative Poisson’s ratio (NPR).

Disordered auxetic metamaterials architected by random peanut-shaped perturbations
Materials & Design, 2021 Previous discussions about perforated auxetic metamaterials primarily focused on the ordered systems with high degree of geometric symmetry. However, it is difficult to manufacture or retain the perfect auxetic systems in practical applications.

Development, fabrication and mechanical characterisation of auxetic bicycle handlebar grip
Scientific Reports, 2023 The auxetic cellular structures are one of the most promising metamaterials for vibration damping and crash absorption applications. Therefore, their use in the bicycle handlebar grip was studied in this work. A preliminary computational design study was
