Abstract:
... Two-dimensional lattice structures with specific geometric features have been reported to have a negative Poisson’s ratio, termed as auxetic metamaterials, that is, stretching-induced expansion in the transversal direction. In this paper, we designed a novel auxetic metamaterial; by utilizing the shape memory effect of the constituent materials, the in-plane moduli and Poisson’s ratios can be cont ...
