Auxetic Textile Materials - A review

Journal of Textile Engineering & Fashion Technology, 2016
Auxetic textiles are materials which possess negative Poisson’s ratio, this implies that in contrast to conventional textile materials if they are stretched in longitudinal direction, a marginal expansion will results in transversal direction. Auxetic textile materials have become a point of focus for many researchers in recent past years.

Study on the Size Effect of Auxetic Cellular Materials

International Journal of Applied Mechanics and Engineering, 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 structure under the typical loading exerted by the compression and simple shearing test ...
