Table 4 Comparison of band gap sizes and frequency ranges in simple cubic lattice.
From: Optimal design of lattice structures for controllable extremal band gaps
Band gap # | Band gap size | Lower bound of band gap | ||
---|---|---|---|---|
(Hz) | Mode # | Frequency (Hz) | ||
Original undulated design | 1 | 387.9 | 15 | 3198.9 |
2 | 24.9 | 16 | 3875.1 | |
Optimal design | 1 | 853.7 | 15 | 165.6 |
