Materials Science-Poland, 2013 Auxetic materials are endowed with a behavior that contradicts common sense, when subjected to an axial tensile load they increase their transverse dimension. In case of a compression load, they reduce their transverse dimension. Consequently, these materials have a negative Poisson’s ratio in such direction.

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 ...

Auxetic Materials and Related Systems [PDF]
physica status solidi (b), 2014 to mechanical metamaterials and related systems with particular emphasis on auxetic systems. Such materials show counter-intuitive, negative behaviours. For example, auxetic materials exhibit negative Poisson’s ratios which mean that these systems get fatter rather than thinner when stretched.

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.

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.

Random Auxetic Porous Materials from Parametric Growth Processes [PDF]
, 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 ...
