Abstract Scope |
Metamaterials exhibit novel, structure-dependent mechanical properties that are otherwise unobtainable. The mechanical properties of metamaterials are well studied in the quasi-static regime; however, the dynamic deformation of metamaterials is relatively unexplored. A priori, it is not obvious how to extrapolate findings about metamaterials in the quasistatic regime to the dynamic regime. While some individual metamaterial systems have been studied in the dynamic regime, a unifying framework which can explain the exotic behaviors of dynamically loaded metamaterials (such as severe deformation failure modes) would be extremely valuable in designing, optimizing, and exploring these materials. This work seeks to address this need using theoretical and computational methods grounded in experiments over strain rate regimes of 10^1 to 10^3 per second and pressures up to 5GPa.
