摘要:
The idea of manipulating transverse waves by longitudinal vibrations has been proposed in this article. The band structures of distributed resonators on an Euler beam undergoing high frequency longitudinal vibrations have been investigated. The supplement of longitudinal vibration alters the transverse wave band structures by providing pseudo-stiffness. The varying band gaps of both Bragg scattering and local resonance have been studied focusing on the contribution of the longitudinal vibration. The analytical results are validated by the finite element numerical method.
