Metastructures is an emerging research topic that spans several disciplines and that has potentials for impact in a number of engineering systems. These include structures with integrated vibration reduction capabilities, shock absorption, and generally tailored mechanical properties that are derived from the assembly of units at the meso-scale. While some of the concepts rely on, and are inspired by, the abundant literature in the area of metamaterials, there are several aspects in terms of analysis and performance that make metastructures unique. However, the literature on metastructures is at its infancy, and several studies still need to be conducted to fully explore fundamentals as well as areas of application. A 2.5 day workshop brought together experts from academia, industry and government labs with the goal of identifying key research questions and highlighting new areas of investigation based on the opportunities afforded by metastructures concepts. This report summarizes activities conducted during the ARO-sponsored workshop titled Metastructures Dynamics, Topology and Related Opportunities. The workshop was held on May 16-18, 2018, in Atlanta, GA. The workshop included 7 sessions, with a total of 35 presentations by invited speakers from academia and the government. In addition, a breakout session was devoted to the identification of open research questions, application opportunities, and long-term vision for the field of metastructures. Approximately 60 participants were in attendance and actively participated to the technical exchange during and following the presentations, and the breakout session.
