Special Issue Information

Dear Colleagues,

Though there are many world conferences in the field of nondestructive testing and evaluation, there is no bigger conference than WCNDT (World Conference on Non-Destructive Testing). The next world conference, the 20th WCNDT, will be held in Incheon, Korea in 2022 from 28 February to 4 March. This conference is expected to attract 1000 papers, 2000 delegates and over 200 exhibitors from all over the world to showcase the best of the latest innovations and technologies. Additionally, various topics concerning NDT and NDE skills and their applications will be examined, and many excellent papers from those topics are expected to be presented. Among those topics, “Nondestructive Evaluation of Materials”, which is the title of this Special Issue, is a key topic that is highly related with all the fields of nondestructive testing and evaluation, and this is the reason we are opening this Special Issue.

We invite you to submit high-quality research, technical or review papers to this Special Issue, with an emphasis on innovative new and emerging technologies including applications for a wide meaning of nondestructive evaluation of materials. The submission will be open till 30 April 2022 and you can find the details on paper submission on the website (www.wcndt2020.com).

The objective of this Special Issue is to gather the experience of leading scientists, researchers, and field engineers and to support those who would like to adopt a new non-destructive evaluation methodology for better safety as well as production efficiency in industrial fields. From this point of view, we believe that this Special Issue will provide technological advances, and the latest research on the state-of-the-art, and innovative field application results in nondestructive evaluation of materials. Interested and committed individuals from academia, research laboratories, industries, and related companies are invited to contribute by submitting papers to this Special Issue.

If you need any further information about this Special Issue, please do not hesitate to contact us.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Acoustic Emission (AE) is revealed to be highly adapted to monitor materials and structures in materials research and for site monitoring. AE-features can be either analyzed by means of physical considerations (geophysics/seismology) or through their time/frequency waveform characteristics. However, the multitude of definitions related to the different parameters as well as the processing methods makes it necessary to develop a comparative analysis in the case of a heterogeneous material such as civil engineering concrete. This paper aimed to study the micro-cracking behavior of steel fiber-reinforced reinforced concrete T-beams subjected to mechanical tests. For this purpose, four-points bending tests, carried out at different displacement velocities, were performed in the presence of an acoustic emission sensors network. Besides, a comparison between the sensitivity to damage of three definitions corresponding to the b-value parameter was performed and completed by the evolution of the RA-value and average frequency (AF) as a function of loading time. This work also discussed the use of the support-vector machine (SVM) approach to define different damage zones in the load-displacement curve. This work shows the limits of this approach and proposes the use of an unsupervised learning approach to cluster AE data according to physical and time/frequency parameters. The paper ends with a conclusion on the advantages and limitations of the different methods and parameters used in connection with the micro/macro tensile and shear mechanisms involved in concrete cracking for the purpose of in situ monitoring of concrete structures.

The CLP (containment liner plate) of a nuclear power plant protects the internal system from the external environment and sudden changes in internal pressure or temperature, and it is a structure that blocks and protects radioactive materials leaking inside and outside in the event of a nuclear accident and is composed of a liner plate, reinforcing bars, tendons, and concrete. Recently, corrosion on the rear side of the liner plate and concrete voids has emerged as a severe defect in nuclear power plants across South Korea. Therefore, in this study, we proposed a new inspection method that a line-type inspection method applied phased array ultrasonic testing and the area inspection method applied acoustic resonance method using developed moveable tapper. The acoustic signals were signal-processed and reproduced to a mapping image following the inspection area, and with the image, it was possible to determine the type of defect. Furthermore, an automated inspection system for within the CLP was proposed. Full article
