Abstract
Metamaterials are a class of material with properties that do not occur naturally or are not obtained from their constituent materials. In this work, the effects of an array of linear resonators (locally resonant metamaterial) on the mechanical and aeromechanical behavior of a plate-like wing model are investigated. Finite element simulations are performed using the commercial software Nastran along with a self-developed continuous model of a plate. In both cases, the unsteady aerodynamic loads are obtained from the doublet lattice method. The bandgap created by the presence of the array of resonators is compared to theoretical predictions recently discussed in the literature and its consequence to the system aeroelastic behavior is analyzed.
