Vibration attenuation properties of piezoelectric metamaterial plates

Abstract

In this study, a heterogeneous piezoelectric 2-D plate is considered. The particular heterogeneity due to periodically distributed soft elastic cylinders anchored in the plate provides the antiresonance property inducing a non-dissipative damping within specific frequency ranges called band gaps, where the standing or propagating waves are suppressed. This paper examines different mechanisms for controlling band gap properties and investigates their influences on band gap characteristics. Finally, the band gaps are utilized for controlling the propagation of vibration waves along the piezoelectric plate in the frequency domain.
