Mechanical properties of 3D re-entrant honeycomb auxetic structures realized via additive manufacturing (2015, methodology): “Several researchers employed the large deflection model for the 2D re-entrant honeycomb and derived expressions for Poisson’s ratios in the two principal directions (Levy and Goldfarb, 2006; Wan et al., 2004).”
Auxetic mechanical metamaterials (2017, unknown): “62 According to Wan et al. (2004), the Poisson's ratios are non-linearly dependent on strain at large deformation and vary from positive to negative in response to the geometrical changes presented by Yang et al. (2003).”
A review on auxetic structures and polymeric materials (2010, background): “The Poisson's ratio ( ) of a material is defined as the negative ratio of the transverse strain to the axial strain in the direction of loading (Wan et al., 2004).”
Review of Mechanics and Applications of Auxetic Structures (2014, background): “In other words, the magnitude of Poisson’s ratio decreases significantly at high strain when the auxetic honeycomb is compressed in X-direction loading or stretched inY-direction loading, while it increases significantly at high strain when the auxetic honeycomb is stretched in X-direction loading o”
A Comparative Study of Ballistic Resistance of Sandwich Panels with Aluminum Foam and Auxetic Honeycomb Cores (2013, background): “Up to date, research work of the auxetic materials are mainly concentrating on the cell design [15–17] and the static and dynamic responses [18–25], although the auxetic materials also demonstrate strong potentials for energy absorption, fracture retardant, and ballistic resistance [26, 27].”
Designable dual-material auxetic metamaterials using three-dimensional printing (2015, background): “Those parameters include angles at hinges [22] and [23], diameters of beams [24] and length ratio of beams [25].”
The influence of cell micro-structure on the in-plane dynamic crushing of honeycombs with negative Poisson’s ratio (2015, background): “The results above show that cell micro-structures (such as, the porosity, h/l and ) have a very significant effect on the macro-/micro- mechanical properties of auxetic foams [10, 12, 15].”
