To achieve wave attenuation at ultra-low frequencies, a novel metamaterial plate with
attached compliant quasi-zero-stiffness (QZS) resonators is proposed. Firstly, the compliant …

We investigate the complex band structure and forced response of flexural waves
propagating in an elastic metamaterial thick plate. Mindlin-Reissner thick plate theory is …

Elastic wave propagation characteristics of elastic metamaterial plates embedded scatterer
with various lattices are explored numerically and experimentally in this study, for the …

Artificial structures known as phononic crystals and acoustic metamaterials can be designed
by spatially arranging one or more materials to obtain desired wave manipulation …

Low-and mid-frequency range vibrations usually present issues in their insulation. The
development of periodic metamaterials (artificially engineered structures) has been …

Inversely designing and optimizing topological structures of phononic crystals that dominate
extraordinary wave characteristics has become a research hotspot. In this study, a joint …

Metastructure has been discovered as a new and effective means of vibration suppression
in recent studies. Based on the basic principle of the locally resonant (LR) metastructure, a …

Periodic structures can be used for vibration control thanks to their vibration attenuation stop
bands. The dispersion diagram obtained for the structural unit cell can be used to …

The design of structures that can yield efficient sound insulation performance is a recurring
topic in the acoustic engineering field. Special attention is given to panels, which can be …

This paper presents an isogeometric shape optimization methodology to widen the band
gap of periodic composite plates by smoothly optimizing its thickness profile. To save the …
