Study of the effect of specimen size and frequency on the structural damping property of beam

open access: yesMechanical Engineering Journal, 2016
It is said that the parameters that characterize structural damping, i.e., the loss factor, are identical to the material of the specimen, but in actuality, the damping property is sometimes affected by specimen size or the frequency.

Effect of viscoelastic polymer on damping properties of precast concrete panel

open access: yesHeliyon, 2021
Precast concrete system has been widely used in modern day constructions due to its high efficiency in both production time and cost. However, because of the way it is constructed (with flat and dense surface), problems with sound reflection and ...

Reconstruction of damping properties for bended specimen

open access: yesNihon Kikai Gakkai ronbunshu, 2021
A general machine or structure is manufactured by combining a plurality of members, and these members may be used as they are in a simple shape or may be used after being shaped. When performing the dynamic design of such machines or structures by Finite

Use of viscoelastic polymer sheet as an acoustic control treatment in ceramic tiles to improve sound insertion loss

open access: yesResults in Engineering, 2023
Ceramic tiles are commonly used in non-structural components of a building such as walls, partitions, floors, and roofs. However, due to their high surface hardness and density, ceramic tiles are not an ideal soundproof material.

A Study on the Damping Capacities of Mg–Zn–Y-Based Alloys with Lamellar Long Period Stacking Ordered Phases by Preparation Process

open access: yesMetals, 2021
Mg alloys with fine mechanical properties and high damping capacities are essential in engineering applications. In this work, Mg–Zn–Y based alloys with lamellar long period stacking ordered (LPSO) phases were obtained by different processes. The results
