Embedded Ultrasonic Nondestructive Evaluation: Challenges and Solutions

Dear Colleagues,

Embedded ultrasonic nondestructive evaluation (e-NDE) is an NDE method which utilizes embedded ultrasonic transducers that are permanently attached to the structure and can be interrogated on-demand, i.e., active structural health monitoring (SHM). With the remarkable progress that has been made in embedded ultrasonic NDE development, considerable work remains to be done, such as the refining of the theoretical analysis and calibration against well planned experiments, developing novel acoustic sensors for industrial and commercial applications, addressing the operational and environmental variations to deploy e-NDE techniques for in-service structures, developing signal analysis methods to achieve a probability of detection, and developing novel imaging algorithms to quantify the damage detection. Papers on topics including but not limited to one or several of the following aspects will be considered for publication:

• Theory, modeling, and simulation;
• Guided wave actuation and detection;
• Acoustic sensors for industrial and commercial applications;
• Novel signal processing methods;
• Damage detection under operational and environmental variations;
• Guided-wave damage interaction analysis;
• Imaging algorithms for damage quantification;
• Damage detection in composite structures.

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. Sensors 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 2600 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.
