Abstract
In this paper, we present a theoretical investigation of flexural wave propagation and vibration bandgap properties in corrugated-core sandwich metabeam with inertial amplified resonators. The complete analytical solutions for the flexural wave propagation with free boundary conditions are obtained through the spectral element method. Finite element calculation of transmission characteristics of sandwich metabeam with inertial amplified resonators are carried out to validate the accuracy of the proposed complete analytical solutions. In addition, the vibration reduction effect of sandwich metabeam with inertial amplified resonators is compared with that of the corrugated-core metabeam with local resonance. The influences of system parameters on the flexural wave attenuation are analyzed. Results show that the complete analytical solution for the proposed sandwich metabeam structure can be effectively used to predict the vibrational properties. In addition, significant enlargement of low-frequency bandgap can be obtained by using an inertial amplification sandwich metabeam structure. The proposed sandwich metabeam structure has good bandgap adjustment ability.
