This grant investigated the use of active and passive repeated lattice structures to provide vibration suppression in the context of mechanical metamaterials. The major accomplishments are providing vibrations suppression without increasing mass, discovering that linear varying of absorber frequencies results in broadband suppression, created an experimentally validated model of mechanical metamaterials, characterized the damping properties of 3D printed metamaterial systems, determined the dividing line between using a single attached absorber versus a mechanical metamaterial, and developed an active mechanical metamaterial to mitigate temperature effects.
