Pendulum-type elastic metamaterial for reducing the ...

Sep 01, 2019· As discussed in Section 3, we confirmed that the bandgaps of the pendulum-type elastic metamaterial occur because of the string modes. The bandgaps attenuate the vibrations in a specific frequency range, thus the broader and the lower bandgaps are more effective in order to reduce the transverse vibration due to meteoroid collisions.

(PDF) FREE UNDAMPED AND DAMPED VIBRATIONS Lab Report ...

In a free vibration, the system is said to vibrate at its natural frequency. However, due to various causes there will be some dissipation of mechanical energy during each cycle of vibration and this effect is called "Damping." (Ryder and Bennett, 1990). Theoretically, an un-damped free vibration system continues vibrating once it is started.
