An auxetic structure expands in the transverse direction while being stretched in the longitudinal direction. Although the material could have a positive Poisson’s ratio, the overall geometry exhibits a negative Poisson’s ratio effect. Due to this unique property, the auxetic structure is widely applied to sports. This lesson illustrates a simulation of the auxetic structure of a shoe base.
