Robust flexural wave energy harvesting via topologically protected interface modes of defect-enhanced performance in a phononic crystal beam-foundation system
Jianfei Wang, Xiaomin Yang, Zhishen Sun, Zhenyu Chen, Dongxing Cao
Abstract Topologically protected interface modes (TPIMs) offer a novel approach to concentrate vibration energy in the structural interfaces with robustness to defects and disorders preserved, but seldom validated via high-frequency experiment. This paper proposes a flexural wave…
