Meta-structures:Dynamics, Topology and Related Opportunities
Abstract
Meta-structures 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 mesa-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 analy?sis and performance that make meta-structures unique. However, the literature on meta-structures is at its infancy, and several studies still need to be conducted to fully explore fundamentals as well as areas of application. For example, performance of interest may extend well beyond vibrations, given the evidence that meta-structure concepts could be employed to tailor buckling, fracture; and failure mechanisms in structural components. In addition, several opportunities are afforded by the study of geometrical and band topologies, as well as by meta-structures unique, intrinsic dynamic characteristics which often need to account for nonlinearities. Finally, open research questions are related to the presence of interfaces and of interactions between meta-structures and the surrounding environment. Exploration of such interactions and the potential for affecting friction and possibly drag is an open, exciting area of research, along with the investigation of meta-structures with properties that are affected by the flow conditions they operate in. The proposed workshop provides a forum for researchers and engineers to discuss objectives, tools, fundamental questions and poten?tial application areas for meta-structures. This 2. 5 day, single session workshop will bring together experts from academia, industry and government labs with the goal of identifying key research ques?tions and possibly highlighting new areas of investigation based on the opportunities afforded by meta-structures concepts.
