Wave attenuation, filtering and guiding is an ongoing topic of scientific
research, as there are many opportunities for improvement of existing
solutions in modern industry. One of the recent advancements has been made
with the use of non-reciprocal metamaterials.Certain properties of metamaterials
have made them suitable for use in various engineering fields. In this study,
we investigate non-reciprocal wave propagation behavior in coupled thin beams
phononics, due to time-modulation of material properties and axial loads. We
compare the results for the beams which are interconnected with Winkler’s
type of elastic layers and elastic or viscoelastic Pasternak layers. An analytic
approach is used to discover directional band gaps and investigate wave propagation
through these systems of beams, at relevant excitation frequencies. The
proposed framework can be exploited in further analysis of phononic systems
based on multiple beams coupled through different mediums and struct...ural
elements modeled with higher-order beam theories.
