Chirality-induced tension–rotation coupling in cylindrical kirigami structures

Abstract Kirigami, a class of metamaterials composed of elastic sheets with periodic cuts, enables significant in-plane compliance through out-of-plane buckling. This study comprehensively investigates the mechanics and kinematics of chiral cylindrical kirigami structures, demonstrating the emergence of spontaneous rotational deformation under axial stretching. Experimental results reveal that the geometric constraints of the cylinder transform standard tension–torsion coupling into a macroscopi
