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 ...

Review of Mechanics and Applications of Auxetic Structures
Advances in Materials Science and Engineering, 2014 One of the important mechanical properties of materials is Poisson’s ratio, which is positive for most of the materials. However, certain materials exhibit “auxetic” properties; that is, they have a negative Poisson’s ratio.

Dynamic response of auxetic structures [PDF]
Vibroengineering Procedia, 2020 Auxetic materials have been investigated since the 1990’s, they are defined by a negative Poisson’s ratio which gives them interesting capabilities in energy and shock absorption. They are usually lattice structures (2D or 3D array of unit cells), which gives them high stiffness to weight properties and their properties can be tuned to suit a given ...

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.
