Elasticity of anti-tetrachiral anisotropic lattices (2013, background): “Therefore, the through-thickness mechanical performance could be improved through the selection of special geometry parameters related to the nodes and ligaments (Alderson et al., 2010b; Gaspar et al., 2005; Scarpa et al., 2007).”
Auxetic mechanical metamaterials (2017, unknown): “67 Since the re-entrant hexagonal honeycomb can be considered as a structure made from “ arrow-shaped building blocks ” , the auxetic potential of other such periodic structures was explored by Grima et al. (2005).”
A systematic approach to identify cellular auxetic materials (2015, methodology): “From the 9th eigenmode we get some structure related to the lozenge grid square [22, 23, 26].”
Elasto-static micropolar behavior of a chiral auxetic lattice (2012, methodology): “Classical elasticity theory has been previously and successfully used to describe an equivalent continuum with auxetic properties (Gaspar et al., 2005; Grima et al., 2008; Lakes, 1991; Prall and Lakes, 1997; Smith et al., 2000; Theocaris et al., 1997).”
A review on auxetic structures and polymeric materials (2010, background): “According to the analysis (Smith et al., 2000; Gaspar et al., 2005), the structure in Figure 2e exhibits higher auxetic effect than that of the structure in Figure 2d under the same strain.”
The transverse elastic properties of chiral honeycombs (2010, background): “Auxetic behaviour in honeycombs can be achieved via specific cell geometries, including centre-symmetric re-entrant bow tie shaped cells [4,12] which exhibit reflective and rotational symmetry, or by non centre-symmetric chiral cells [13–20],which have rotational symmetry but not reflective symmetry”
Negative Poisson’s Ratio Weft-knitted Fabrics (2010, background): “where xk and yk are the distances between the markers in the wale and course directions at the kth deformation step, and x0 and y0 are the original distances between the markers in these two directions, respectively [17].”
