| Abstract Scope |
Phononics are a sub-class of metamaterials capable of manipulating acoustic waves in solids. In the case of polymer constituents, the dynamic characteristics of phononic structures are dependent on the viscoelastic properties of the polymers. In this talk, we analyze these dependencies for phononic plates made of pristine polymer sheets and for additively manufactured three-dimensional phononic configurations produced by means of commercial FDM, SLS, and MJF techniques. We propose a general finite-element framework to characterize the wave dispersion and transmission in polymer phononic materials with different architectures and validate the obtained results experimentally. The key findings of our study provide useful guidelines for modeling phononics in broad frequency ranges for a variety of applications. |
