In recent years, increasing attention has been paid to the impacts of environmental noises
on living creatures as well as the accuracy and stability of precise instruments. Due to …

Honeycomb composites have been widely used in aerospace, transportation and other
fields due to the excellent mechanical and acoustic properties. Acoustic properties are …

We propose a perforated metastructure combining fish-belly panels and a corrugated
sandwich structure for broadband sound absorption. The curved panels provide a new …

A hexagonal honeycomb sandwich panel with rough embedded necks is proposed as a
new structure for broadband low-frequency sound absorption. A theoretical model is …

This paper proposed a type of lightweight multilayer honeycomb membrane-type acoustic
metamaterials (AMs) and the transmission loss is studied experimentally. It is demonstrated …

The sound absorption performance of micro-perforated plate (MPP) is mainly restricted by
four parameters: cavity depth, aperture, plate thickness and perforation rate. The concept of …

To targeted regulate and improve the low-frequency sound insulation performances of
traditional sandwich structures, a sandwich structure compounded with resonant acoustic …

Influence of perforations having arbitrarily varying cross-sections on the acoustic behaviour
of 3D printed bio-degradable panels made of Poly Lactic Acid (PLA) is presented. Circular …

The main objective of this paper is focused on the vibration behavior analysis of functionally
graded material (FGM) sandwich joined conical–conical shell surround by elastic …

This paper presents analytical studies on the dynamic instability of functionally graded
material (FGM) sandwich conical shell subjected to time dependent periodic parametric …
