Attenuation Characteristics of Vibration in a Locally Resonant Phononic Crystal Frame Structure
Archives of Acoustics, 2020 In this paper, a frame structure based on the locally resonant (LR) mechanism of phononic crystals (PCs) is designed on account of the wide application of frame structures in high-rise buildings, and the band structures, displacement fields of eigenmodes,
