To enhance the sound insulation performance of double panel partitions at their mass-air-
mass resonance frequency, novel compact and low-mass solutions are sought. This paper …

Phononic metamaterials are capable of manipulating mechanical wave propagation in
applications ranging from nanoscale heat transfer to noise and vibration mitigation. The …

We experimentally and numerically investigate elastic wave propagation in a class of
lightweight architected materials composed of hollow spheres and binders. Elastic wave …

Aiming to attenuate very low-frequency flexural wave in a thin plate, this paper proposes a
meta-plate model by periodically attaching high-static-low-dynamic-stiffness (HSLDS) …

Phononic band gaps are investigated in a one-dimensional (1D) array of compliant axial to
rotary motion conversion mechanisms. To create low frequency band gaps, the effective …

This paper investigates a metamaterial solution for efficient vibration attenuation and
acoustic radiation reduction of an aluminum pipe. To this end, using unit cell predictions …

This paper designs the laminate acoustic metamaterials with multi-stopband for structural-
acoustic coupled system. The laminate acoustic metamaterials are composed of carbon …

This paper presents the modeling technique, design method, a new working mechanism
and influence factors for elastic metamaterials (EMs) with parallel multi-resonators for …

Pile barriers as an effective method for isolating ambient vibration have been used in
practical engineering for many decades. However, the study of multiple rows of pile barriers …

A novel small size multi-band gaps phononic crystal (hPC) composed of the periodic
plumbum and aluminum mass has been investigated in this paper, we calculated the …
