A new auxetic structure with significantly reduced stress concentration effects
Materials & Design, 2019 Auxetic structures exhibit certain abnormal mechanical responses such as negative Poisson's ratios, mainly through the intertwined deformation attributes of inter-connected members of macro structural forms.

Dynamic Deformation Behaviour of Chiral Auxetic Lattices at Low and High Strain-Rates
Metals, 2020 The mechanical behaviour of three different auxetic cellular structures, hexa-chiral 2D, tetra-chiral 2D and tetra-chiral 3D, was experimentally investigated in this study.

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 ...

Universal Negative Poisson Ratio of Self Avoiding Fixed Connectivity Membranes [PDF]
, 2001 We determine the Poisson ratio of self-avoiding fixed-connectivity membranes, modeled as impenetrable plaquettes, to be sigma=-0.37(6), in statistical agreement with the Poisson ratio of phantom fixed-connectivity membranes sigma=-0.32(4).

Deformation mechanisms leading to auxetic behaviour in the α-cristobalite and α-quartz structures of both silica and germania [PDF]
, 2008 Analytical expressions have been developed in which the elastic behaviour of the α-quartz and α-cristobalite molecular tetrahedral frameworks of both silica and germania are modelled by rotation, or dilation or concurrent rotation and dilation of the ...

Development of a textile structure for multi-directional auxetic deformation
Materials & Design, 2022 Previous studies of auxetic composites reinforced with woven fiber structures focused on unidirectional tension or compression. Multiple fibers are often required to play different roles in the structure, making it difficult to fully exploit the ...
