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 ...

A novel mechanism for generating auxetic behaviour in reticulated foams : missing rib foam model [PDF]
, 2000 Foams have previously been fabricated with a negative Poisson's ratio (termed auxetic foams). A novel model is proposed to explain this and to describe the strain-dependent Poisson's function behaviour of honeycomb and foam materials.

Novel polyhedral mechanical metamaterial exhibiting negative Poisson’s ratio
Smart Materials and Structures, 2023 Abstract The work presents a novel polyhedral mechanical metamaterial based on rotating triangular prisms connected by their corners, which possesses the ability to attain large values of negative Poisson’s ratio (NPR). Through a kinematic model of the proposed rotating structure, we evaluate the auxeticity of the system by varying the ...

INVESTIGATION OF THE AUXETIC BEHAVIOR OF AN ORIGINAL LATTICE STRUCTURE DESIGN
Gazi Üniversitesi Fen Bilimleri Dergisi, 2023 Auxetic structures are special structures with negative Poisson's ratio due to their geometric shapes in their internal structure. When tensile force is applied to these structures, transverse and longitudinal expansions are observed, while transverse ...
