3D soft metamaterials with negative Poisson's ratio.
Buckling is exploited to design a new class of three-dimensional metamaterials with negative Poisson's ratio. A library of auxetic building blocks is identified and procedures are defined to guide their selection and assembly. The auxetic properties of these materials are demonstrated both through experiments and finite element simulations and exhibit excellent qualitative and quantitative agre...
متن کاملMetamaterials: Snapping Mechanical Metamaterials under Tension (Adv. Mater. 39/2015).
By exploiting snap-through instabilities, D. Pasini and co-workers design a damage-tolerant mechanical metamaterial that snaps sequentially under tension, thereby accommodating a very large deformation up to 150%. On page 5931, they describe how the nonlinear mechanical response of the metamaterial can be robustly programmed by tuning the architecture of its unit cell.
متن کاملReentrant Origami-Based Metamaterials with Negative Poisson's Ratio and Bistability.
We investigate the unique mechanical properties of reentrant 3D origami structures based on the Tachi-Miura polyhedron (TMP). We explore the potential usage as mechanical metamaterials that exhibit tunable negative Poisson's ratio and structural bistability simultaneously. We show analytically and experimentally that the Poisson's ratio changes from positive to negative and vice versa during it...
متن کامل* 3 D Soft Metamaterials with Negative Poisson ’ s Ratio A TIO
A IO N When materials are uniaxially compressed, they typically expand in directions orthogonal to the applied load. Here, we exploit buckling to design a new class of three dimensional metamaterials with negative Poisson's ratio that contract in the transverse direction under compressive loading regimes. These proposed metamaterials consist of an array of patterned elastomeric spherical shells...
متن کاملDesign of Dual-Band Double Negative Metamaterials
A dual-band artificial magnetic material and then a dual-band double-negative metamaterial structure based on symmetric spiral resonators are presented. An approximate analytical model is used for the initial design of the proposed structures. The electromagnetic parameters of the proposed metamaterial structure retrieved using an advanced parameter retrieval method based on the causality princ...
