Acoustic Emission and Related NDT for Structural Integrity and Condition Monitoring

Dear Colleagues,

The importance of engineering structures in contemporary civilization is huge when someone considers the human activity that they support. Non-problematic fullfilment, as well as possible extension of their designed life, is a strong pylon of sustainability as it contributes to usage of less raw materials, while it ensures safety for the public and saving of resources. In order to assure the structures’ status, monitoring technologies are paramount. Among them, acoustic emission (AE) has evolved as a crucial player due to its non-invasive nature, sensitivity and practical use. It is utilized in any field and type of structure providing unique information, complementary to other techniques. Advances in the field of monitoring are fast, coming either from the innovative materials to be inspected, advancements in the technology itself, like new sensors, wireless and contactless reception, or in processes such as the recently emerging applications in additive manufacturing, concrete curing, or cavitation of plants.

The present Special Issue aims to explore the new developments related to acoustic monitoring of materials and structures with AE as standalone technique or in combination with other optical, elastic, and electromagnetic techniques.

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 250 words) can be sent to the Editorial Office for assessment.

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.
