| Abstract Scope |
Tailoring the geometry of mesostructured mechanical metamaterials has enabled unprecedented material properties. Despite this progress, however, systematically designing materials for prescribed dynamic behavior remains a challenge. Here, we first discuss using a reduced-order discrete element model to identify desirable nonlinear constitutive behaviors in a mass-spring chain. We will then discuss a variety of approaches to achieving the desired effective constitutive behavior in physical structures (e.g. analytically, via finite element method parametric studies, or via topology optimization). We also consider broader implications for impact mitigation, computing, and signal processing fields. |
