Auxetic mechanical metamaterials (2017, neutral): “Masters & Evans (1996)  nally combined all three deformation mechanisms to form a general model in 2D. 35 Broken cell ribs were observed in processed foams by Smith et al. (2000), who proposed a two-dimensional missing rib foam model.”
Poisson's ratio and modern materials (2011, background): “1b (horizontal axis), materials are extremely compressible, examples being re-entrant foams and molecular structure”
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).”
Auxetic materials and their potential applications in textiles (2014, methodology): “A missing rib 2D model that could better predict the NPR and stress– strain behavior of auxetic foams was proposed by Smith et al.69 The limit of the 2D model is that it can only be used to predict the in-plane behavior, and the out-of-plane behavior is completely ignored.”
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”
Homogenization of periodic hexa- and tetrachiral cellular solids (2014, background): “The auxetic effect occurs in cellular materials, such as foams (see Lakes, 1987), honeycomb structures and networks (Smith et al., 2000) and origami structures (Schenk and Guest, 2013), as the result of the unfolding of re-entrant cells as they are stretched.”
