Abstract: | The study analyses the dynamic behaviour of a smart metamaterial beam coupled with piezoelectric in shunt configuration and periodic characteristics for attenuation in wave propagation. The periodic arrangement of shunted of piezoelectric shunt patches incorporated to a beam undergoing transverse motion provides attenuation properties to the beam linked to the resonant behaviour of the shunts. A stop-band or bandgap is created in the structure elastic wave through because of the periodic configuration leading to a wave control. The spectral element method that is accuracy technique to perform the dynamic analysis is used to model the smart metamaterial beam. A numerical model predicts the flexural wave behaviour of the beam for different shunting configurations. |
