A bibliometric analysis of research on acoustic emission for nondestructive testing

Abstract

Acoustic emission (AE) testing has been an active area of research globally for many decades. The present work is a comprehensive overview based on bibliometric analysis to investigate the application of AE research. The publication trends, key areas, organizations, countries, and sources and publications of AE applications are presented to address the following basic questions: what are the publication sources and trends, what are the key areas, and which countries and organizations are active in AE research? The influences of various AE subjects and topics are also discussed. With the help of the Web of Science Core Collection database and the specialized bibliometric analysis tool VOSviewer, the results are visualized properly, and it is found that AE research is currently developing rapidly.

Industrial Revolution 4.0: Reconnaissance of Opportunities and Challenges for Smart Sustainable Cities

“…The foundation of VOS mapping is the generation of association normalization similarity matrices. For a network of n nodes, s ij ∈S signifies the similarity or association strength of nodes i and j in a network of n nodes using Equation 1 (van Eck & Waltman, 2014, 2020Yan et al, 2021).…”

“…After constructing the similarity matrix, VOS mapping uses distancebased mappings to locate node i in a p-dimensional map (typically p = 2), Equation 2. On the other hand, VOS clustering conducts clustering analysis by a maximizing method comparable to modularity-based clustering (van Eck & Waltman, 2014, 2020Yan et al, 2021).…”

“…where c i is the cluster of the i th node, the result of δ(c , ,c j ) is a perfect one if c i = c j or zero otherwise, and γ is the clustering resolution (van Eck & Waltman, 2014, 2020Yan et al, 2021).…”

Resistivity Method Evaluation of Corroded OPS-Concrete

“…Resistivity is one of the Non-Destructive Testing (NDT) methods widely used to evaluate the resistance of concrete with low cost, fast and easy to apply in the laboratory and the field [14][15][16][17][18]. This method can determine the quality of the component without affecting the ability and function of the service on the building structure [19]. Before steel corrosion started, RC's electrical resistivity (ER) was thought to be a good indicator of the corrosive environment.…”
