Abstract: The chiral mechanism of slanted-rod compression-torsion coupled metamaterials has been studied. Multiple geometric configurations of metamaterials with 2D (non-)chiral honeycomb structures were designed by altering the connecting methods of ligaments. Finite element simulations indicate that the ligaments not only connect the structure and transmit forces and moments but also can alter the deformation modes of the structure. Ligaments with chiral distribution exhibit better mechanical performance during the deformation process, outperforming those without chiral distribution. The asymmetric deformation of upper and lower ligaments in CSCM-T (chiral stretched-compressed metamaterial-tangential), which features offset and compressed circular rings, results in the highest ultimate bearing capacity and axial stiffness among all studied designs. Both CSSM-T (chiral stretched-stretched metamaterial-tangential) and CSCM-T demonstrate excellent energy absorption performance, and a closer centroids of adjacent circular rings leads to better energy absorption performance of CSSM-T. This design approach provides a new solution for optimizing lightweight and high-strength metamaterials.
