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 ...

Elasto-plastic shear behavior of reinforced honeycomb and auxetic reentrant lattices
Millenium, 2018 Introduction: Auxetic materials possess a negative Poisson’s ratio. Even though, the existence of isotropic auxetics is theoretically possible, they seem to be absent in natural states thus, there has been an effort to produce artificial auxetics mostly ...

Random Auxetic Porous Materials from Parametric Growth Processes
, 2021 International audienceWe introduce a computational approach to optimize random porous materials via parametric growth processes. We focus on the problem of minimizing the Poisson's ratio of a two-phase porous random material, which results in an auxetic ...

Modelling of auxetic foam embedded brittle materials and structures
, 2016 Building structures use brittle materials extensively. Under impact or blast loads these structures perform poorly due to tensile strains caused by Poisson’s effect normal to the direction of such loadings.

Elasticity of Auxetic Materials
, 2023 The auxeticity of elastic materials is described and explained by the use of the linear and nonlinear models of elastic deformations for a wide range of strain values up to moderate levels. This chapter consists of three parts – general information on auxetic materials, description of auxetics by the model of the linear theory of elasticity ...

Auxetic mechanical metamaterials to enhance sensitivity of stretchable strain sensors
, 2018 Stretchable strain sensors play a pivotal role in wearable devices, soft robotics, and Internet-of-Things, yet these viable applications, which require subtle strain detection under various strain, are often limited by low sensitivity.

Impact absorption in auxetic damageable materials [PDF]
, 2021 In this work we study the behaviour of elastic and quasi-brittle auxetic metamaterial under impact. Particular reference is made to the use of these structured materials for facial protector devices for sport activities.

core
, 2023 Research on auxetic metamaterials is important due to their high performance against impact loadings and their usefulness in actuators, among other applications. These metamaterials offer a negative Poisson’s ratio at the macro level.

Core Spun Based Helical Auxetic Yarn: A Novel Structure for Wearable Protective Textiles
Journal of Natural Fibers, 2022 Textile auxetic materials with negative Poisson’s ratio (NPR) have potential applications in protective textile, filtration, and energy absorbance. However, cotton core-spun based auxetic textile is rarely investigated.
