Journal of Marine Science and Engineering, 2023 In this paper, the negative Poisson’s ratio and rigidity of a protective structure are improved to allow the structure to exert a negative Poisson’s ratio effect in multiple directions and to enhance the structural load-carrying capacity. Therefore, a 3D

Effect of a Negative Poisson Ratio in the Tension of Ceramics [PDF]
Physical Review Letters, 2008 The effect of a negative Poisson ratio is experimentally revealed in the tension deformation of a natural layered ceramic. This effect can increase the volume strain energy per unit volume by 1100% and, simultaneously, decrease the deformation strain energy per unit volume by about 44%, so that it effectively enhances the deformation capacity by about ...

On Surface Waves in Materials with Negative Poisson Ratio
Acta 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.

A novel mechanical metamaterial with simultaneous stretching- and compression-expanding property
Materials & Design, 2021 Poisson’s ratio is an important property defining the relationship between lateral and longitudinal deformations. While most conventional materials have positive Poisson’s ratios, auxetic metamaterials exhibit negative Poisson’s ratios and will contract ...

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