000014890 520__ $$2eng$$aNew chiral structures were designed to enlarge the auxetic effects and create new deformation mechanisms upon external stimuli. A rotational-spring-rigid-rod model was developed to predict the auxetic effects of the new chiral structures. Four new structures from this family were reported in this paper: (1) a regular chiral structure, (2) a chiral structures with hard core, (3) a chiral structure with soft hinges, and (4) a chiral structure with auxetic core. Finite element (FE) simulations and mechanical experiments on 3D-printed specimens were performed to study the mechanics of these structures. The results show that compared with the regular chiral structure, all other three new structures have a smaller Poisson’s ratio. The smaller Poisson’s ratio is attributed to larger rotational ratio between active and passive ribs in the chiral cells. More interestingly, the chiral structure with auxetic cores showed a unique sequential cell-opening mechanism.
