A review on artificial intelligence-enabled mechanical analysis of 3D printed and FEM-modelled auxetic metamaterials

Virtual and Physical Prototyping
Auxetic structures, characterised by a negative Poisson’s ratio, exhibit the unique property of expanding in all directions under tensile loading and contracting in all directions when compressed. The behaviour of these structures is highly influenced by

Circular Auxetic Plates

Journal of Mechanics, 2012
AbstractThis paper investigates the suitability of auxetic materials for load-bearing circular plates. It is herein shown that the optimal Poisson's ratio for minimizing the bending stresses is strongly dependent on the final deformed shape, load distribution, and the type of edge supports.

Auxetic performance

, 2019
Auxetic cell structures are rare in nature, but their structural composition gives them some very special properties. Because, under pressure, they contract in every direction, Auxetics are used to insert medical stent pipes into veins to keep them open.

Introducing Auxetic Behavior to Syntactic Foams

Metals
This paper proposes an innovative multi-material approach for introducing auxetic behaviour to syntactic foams (SFs). By carefully designing the size, shape, and orientation of the SFs, auxetic deformation behaviour was induced. Re-entrant hexagon-shaped

Auxeticity and Wood

Drvna industrija
Poisson’s ratio, one of the elastic constants, describes the ratio of lateral strain to axial strain when a material is subjected to stress. The range of Poisson’s ratios greatly varies in terms of material types and their structures.
