Active and Reconfigurable Topological Mechanical Metamaterials from the Nanoscale to the Macroscale
Abstract
This MURI project aims to greatly expand the new field of activetopological mechanical metamaterials (TMMs) by (1) developing 3D printing and self-assembly systems to fabricate TMMs that are addressable at the nanoscale and scalable to the macroscale; (2) expanding fundamental theories of TMMs, especially ones featuring fractional excitationsthe new frontier of topological states, by taking advantage of recent advances in knowledge of quantum topological states, the vast majority of which remain uncharted territoriesfor mechanics; (3) using artificial intelligence tools to design and realize continuous media TMMs with no open spaces, which will greatly broaden the structural and functional attributes of TMMs compared to traditional cellular designs; and (4) applying the produced TMMs to realize unidirectional and backscattering-free propagation of waves at previously inaccessiblefrequency ranges.
