Onset of criticality in hyper-auxetic polymer networks
Nature Communications, 2022 Auxetic materials are characterized by a negative Poisson’s ratio - they become thicker when stretched. Here, authors reach the limit of auxetic behavior, known as hyper-auxetic, in polymer networks, hitting an unconventional mechanical critical point.

Theory of strains in auxetic materials [PDF]
, 2012 Auxetic materials, or negative-Poisson's-ratio materials, are important technologically and fascinating theoretically. When loaded by external stresses, their internal strains are governed by correlated motion of internal structural degrees of freedom ...

Review of Mechanics and Applications of Auxetic Structures
Advances in Materials Science and Engineering, 2014 One of the important mechanical properties of materials is Poisson’s ratio, which is positive for most of the materials. However, certain materials exhibit “auxetic” properties; that is, they have a negative Poisson’s ratio.
