Multilevel structural defects-induced elastic wave tunability and localization of a tensegrity metamaterial

Defects are generally inevitable when fabricating the constituent structures of tensegrity metamaterials. How structural defects affect the mechanical properties of such metamaterials is an interesting and vital issue, which may provide a new approach for their elastic wave control. We here construct a metamaterial chain composed of two types of prismatic tensegrities, and investigate its bandgap characteristics with considering multilevel...
