Study of mechanical properties and enhancing auxetic mechanism of composite auxetic structures
Engineering Reports, 2021 The auxetic structures attract much attention because of their good properties, such as enhanced energy absorption capacity and buckling resistance. It is an important topic to combine the auxetic structures with other materials or structures to improve ...

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.

Study on the Size Effect of Auxetic Cellular Materials [PDF]
, 2017 The objective of this paper is to investigate the effects of scale of an auxetic cellular material sample on the evaluation of elastic properties. Size and boundary effects are studied in detail. This is achieved by conducting computer simulations of the

Auxetic strains—insight from iso-auxetic materials [PDF]
Molecular Simulation, 2005 Auxeticity is the result of internal structural degrees of freedom that get in the way of affine deformations. This paper proposes a new understanding of strains in disordered auxetic materials. A class of iso-auxetic structures is identified, which are auxetic structures that are also isostatic, and these are distinguished from conventional elasto ...

Towards Polymers with Molecular Auxeticity
CHIMIA, 2019 Abstract: For many decades, it has been challenging to synthesize auxetic materials at the molecular level. Auxetic materials exhibit counterintuitive behavior; they expand perpendicularly to the direction in which they are stretched. An aromatic macrocycle containing a sequence of N-substituted and N-unsubstituted amides was designed to ...
