Auxetic metamaterials and structures: a review (2018, background): “This property is reported to be very useful [220] based on the fact that it provides a way to fabricate a dome-shaped structure with using damaging techniques nor additional machining [221].”
Elasticity of anti-tetrachiral anisotropic lattices (2013, background): “The transverse shear modulus of isotropic anti-tetrachiral lattices is similar to the one of 3-ligaments configurations, and 50% lower on average compared to hexachiral configurations (Lorato et al., 2010).”
Mechanical metamaterials: a state of the art (2019, unknown): “Here, we will focus on some widely recognized structural deformation models, such as re-entrant structures [51, 52], rotating rigid and semi-rigid deformation models [53] and chiral structures [54, 55].”
The in-plane linear elastic constants and out-of-plane bending of 3-coordinated ligament and cylinder-ligament honeycombs (2010, background): “The in-plane and through-thickness linear elastic properties of the 3-, 4- and 6connected chiral and anti-chiral honeycombs have been reported [11,12].”
Auxetic mechanical metamaterials (2017, unknown): “98 Chiral honeycombs were also found to exhibit higher moduli than their anti-chiral counterparts having the same number of ligaments, 98 although contradictory results were presented by Lorato et al. (2010).”
Zero Poisson’s ratio cellular structure for two-dimensional morphing applications (2015, unknown): “The transverse shear modulus has an inverse correlation with the gauge thickness ratio γ, due to the effect of the in-plane bending deformations of the walls [11, 16, 21, 34, 35].”
Homogenization of periodic hexa- and tetrachiral cellular solids (2014, methodology): “This result, which is similar to that of Liu et al. (2012) and Spadoni and Ruzzene (2012), the latter obtained by a different way, shows that the overall Young's modulus and Poisson's ratio of the hexachiral honeycomb are even functions of the parameter of chirality β , thus these moduli are not abl”
A Gradient Cellular Core for Aeroengine Fan Blades Based on Auxetic Configurations (2011, background): “…via the geometric mean of the properties (Ec ExEy, c ffiffiffiffiffiffiffiffiffiffiffiffi xy yx p ) leads to a good approximation of the uni-axial tensile properties and general mechanical behavior of cellular structures made with FDM prototyping (Lorato et al., 2010; Lira and Scarpa, 2010).”
Mechanical metamaterials associated with stiffness, rigidity and compressibility: a brief review (2017, background): “8 [138,141]), where the twodimensional basic units are connected together either with nodes on opposite sides of the ligaments (in the case of the chiral system [142,143]), or with nodes on the same side of the ligaments (in the case of the anti-chiral system [140,144]).”
In-plane elasticity of a novel auxetic honeycomb design (2017, background): “A variety of honeycomb configurations achieving positive/negative/zero Poisson’s ratio have been proposed and investigated with special focus on the in-plane mechanics, flatwise compressive strength and the transverse shear modulus [9-25].”
