Measurement and Characterisation of a Diffuse Acoustic Field Using a Phased Array

open access: yesChinese Journal of Mechanical Engineering, 2021
A diffuse acoustic field has been increasingly used to infer temporal changes in the structures, such as early dislocations and microcracking. This study explores three different techniques to characterise acoustic field by using a single ultrasonic ...

Ultrasonic Phased Array Imaging Approach Using Omni-Directional Velocity Correction for Quantitative Evaluation of Delamination in Composite Structure

open access: yesSensors, 2023
The ultrasonic detectability of buried defects within composite materials is dependent on the anisotropy of the composite material by which the propagation property of acoustic wave in each direction is variably affected.

Leak Localization on Cylinder Tank Bottom Using Acoustic Emission

open access: yesSensors, 2022
In this study, a scheme for leak localization on a cylinder tank bottom using acoustic emission (AE) is proposed. This approach provides a means of early failure detection, thus reducing financial damage and hazards to the environment and users.
