Emerging capability to fabricate well-defined, ordered lattice structures offers opportunity to create new energy absorption materials with previously unachieved properties. Metallic microlattices can be designed to maximize energy absorption while not transmitting a stress greater than the injury or damage threshold. The stress–strain response of different microlattice materials is characterized under quasi-static and dynamic loading and compared to state-of-the-art materials.
