Harnessing out-of-plane deformation to design 3D architected lattice metamaterials with tunable Poisson’s ratio

Abstract Auxetic materials exhibiting a negative Poisson’s ratio are of great research interest due to their unusual mechanical responses and a wide range of potential deployment. Efforts have been devoted to exploring novel 2D and 3D auxetic structures through rational design, optimization, and tak...
