Abstract

Metamaterials are a class of material with properties that do not occur naturally or are not obtained from their constituent materials. Acoustic metamaterials are able to tailor the propagation of elastic waves through the generation of frequency ranges of strong wave attenuation known as bandgaps. The bandgaps are result of wave scattering at periodic impedance mismatch zones (Bragg scattering) or are generated by an array of resonating units. Locally resonant metamaterials are capable of producing low frequency attenuation regions, which have been investigated for vibration control applications. Usually, linear resonating units have been investigated in the literature. In this work, the effects of an array of linear resonating units on the elastic and aeroelastic behavior of a plate-like wing will be investigated. Moreover, the effects of nonlinear resonating units (through the use of nonlinear springs) on the bandgap formation was well as on the elastic and aeroelastic behavior of the plate-like wing will be also investigated.
