Special Issue Information

Dear Colleagues,

This Special Issue presents new ideas and experimental results related to applications of ultrasound non-destructive testing (UNDT). The use of ultrasound is an important technique in NDT, being largely used in industrial contexts. Metal and composite materials used in critical applications, such as aerospace manufacturing, require appropriate NDT to guarantee safety. Thus, research contributions on the latest R&D achievements regarding ultrasonic non-destructive testing and evaluation, as well as the development of new equipment, analyses, and approaches to non-destructive measurements, are encouraged for submission.

Authors are encouraged to submit contributions in any of the following areas related UNDT:

  • Ultrasonic non-destructive testing/ultrasonic non-destructive evaluation;
  • Ultrasonic-based structural health monitoring and damage detection;
  • Material characterization;
  • NDT of composites;
  • Ultrasound phased arrays;
  • Guided waves;
  • Process monitoring;
  • Ultrasound sensors, transducers, and sensor networks;
  • Instruments, devices, and systems for ultrasound research and applications;
  • Ultrasound in civil, aerospace, and geological applications.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Adhesive coatings, including car paints and car putties, have found application in the construction of motor vehicles. This article contains the results of mechanical and ultrasonic tests of the adhesion of the car putty coating to a steel substrate. The main objective of this article is to determine the correlation between mechanical adhesion and the ultrasonic measure of adhesion—the reflection coefficient |r|. The results indicate that with the increase in the value of the coefficient |r|, the mechanical adhesion of the coating to the substrate decreases. The highest average mechanical adhesion of the coating to the substrate was obtained for sandblasted samples and was 2.74 MPa, corresponding to a coefficient reflection value of 0.71. The test results have an important application aspect and may be useful at the stage of assessing the adhesion of adhesive coatings in a non-destructive manner. Full article
