Homogenization of periodic hexa- and tetrachiral cellular solids (2014, background): “…to the chiral topologies, the study of the mechanical behavior of hexachiral structures started from the seminal paper by Prall and Lakes, 1997, and was later developed to include the analysis of damage processes (see Bettini et al., 2010) and of free wave propagation (Spadoni et al., 2009).”
Wave propagation characterization and design of two-dimensional elastic chiral metacomposite (2011, background): “For convenience, the vectors containing generalized nodal displacements u and forces f in the cell are defined in the form [15] u1⁄4 u0 u1 u2 u3 u4 u5 ui T f 1⁄4 f0 f1 f2 f3 f4 f5 f i n oT (10) where subscripts 0–5 identify quantities belongs to six boundary nodes, subscript idenotes quantities of i”
Controllable thermal expansion of large magnitude in chiral negative Poisson's ratio lattices (2015, methodology): “Chiral lattices have been considered for use as chiral honeycomb [13] [14] in sandwich panels for airplane wings that change shape, and they have been analyzed for buckling [15] and other characteristics such as stop bands in wave propagation [16]; they have also been fitted with sensors and actuato”
Chiral three‐dimensional isotropic lattices with negative Poisson's ratio (2016, background): “The lattices exhibit tunable band gaps [14] in wave propagation; potentially useful in reducing vibration.”

Elasto-static micropolar behavior of a chiral auxetic lattice (2012, background): “…a representative auxetic structural network with internal rotational units, known as the chiral lattice is investigated with an equivalent, micropolar-continuum model in an attempt to remove the indeterminacy n ¼ À1 encountered so far (Prall and Lakes, 1997; Spadoni, 2008; Spadoni et al., 2009).”
Chiral effect in plane isotropic micropolar elasticity and its application to chiral lattices (2012, background): “However, when this theory is applied to a planar isotropic case, e.g. a triangular chiral lattice, the variables describing the chiral effect disappear and the resulting theory becomes basically non-chiral (Spadoni and Ruzzene, 2012).”
