Abstract
We propose a design strategy for creating origami-like mechanical metamaterials with diversenon-linear mechanical properties and capable of remote actuation. The proposed triangulated cylindricalorigami (TCO)-inspired metamaterials enable the highly desirable strain-softening/hardening and snap-through behaviors via a multi-material and highly deformable hinge design. Moreover, we couple thesenovel non-linear mechanical properties of the TCO origami-inspired metamaterials with thetransformative ability of hard-magnetic active materials, allowing for untethered shape- and property-actuation in the developed metamaterials. We develop a mathematical modeling framework for theproposed TCO origami-inspired metamaterials, building on approximating the highly deformable hingesas a combination of longitudinal and rotational springs. We validate the accuracy of the developedmathematical modeling approach by comparing the analytically predicted compressive response of a unitcell structure with the corresponding numerical and experimental results. Using the developedmathematical modeling framework, we investigate the magnetic field-induced large deformation andsuperimposed solitary wave propagation in the TCO origami-inspired metamaterial system. We showthat the proposed metamaterial allows us to tune the key characteristics of the enabled non-linear solitarywaves, including their characteristic width and amplitude. The proposed design strategy for readilymanufacturable origami-inspired metamaterial systems paves a novel path for practical engineeringapplications. Our studies also underscore the potential of magneto-mechanical interaction in the designof reconfigurable metamaterial systems with superior non-linear mechanical and elastic wave properties.
