A new auxetic structure with significantly reduced stress concentration effects
Materials & Design, 2019 Auxetic structures exhibit certain abnormal mechanical responses such as negative Poisson's ratios, mainly through the intertwined deformation attributes of inter-connected members of macro structural forms.

Auxetic tubular scaffolds via melt electrowriting
Materials & Design, 2020 Auxetics are an interesting class of materials that expand in transverse directions when tensile loading is applied. For example, in contrast to conventional materials, an auxetic tube will increase in diameter when stretched along its axis.

A class of auxetic three-dimensional lattices
, 2015 We propose a class of auxetic three-dimensional lattice structures. The elastic microstructure can be designed in order to have omni-directional Poisson's ratio arbitrarily close to the stability limit -1.
