Numerical investigation of rate and scale effects in architected metamaterials under high-rate loading conditions
conference paper
The introduction of advanced manufacturing technologies has made architected metamaterials widely available for use in a variety of applications. Of these applications, impact mitigation in sports, space, and military contexts is of particular interest. Herein, rapid loading regimes may lead to both material and geometric nonlinearities. While the behavior of architected materials in static conditions has been widely documented, the dynamic response remains largely unexplored. In the dynamic regime, investigations tend to focus on the global response of the structure for impact mitigation [1]. However, the meso-structure of the architected material has been shown to exert a significant influence on the overall response [2].
