On Surface Waves in Materials with Negative Poisson Ratio

open access: yesActa Physica Polonica A, 2009
Auxetics are the materials that get fatter when stretched. This counterintuitive property is quantitatively rendered by a negative Poisson ratio. The latter is defined as the quotient of the linear perpendicular contraction to the expansion parallel to the axis of an applied uniaxial tensile stress.

Hierarchical Fibers with a Negative Poisson’s Ratio for Tougher Composites [PDF]

open access: yesMaterials, 2013
In this paper, a new kind of hierarchical tube with a negative Poisson’s ratio (NPR) is proposed. The first level tube is constructed by rolling up an auxetic hexagonal honeycomb. Then, the second level tube is produced by substituting the arm of the auxetic sheet with the first level tube and rolling it up. The Nth (
