The meeting is open to all individuals interested in acoustic emission technology and applications.


We would like to inform you that the AEWG-63 meeting has been postponed to 2022 due to the increase of Covid-19 cases in the U.S.

We will determine the meeting dates early 2022 depending on the course of pandemic, and then inform the community.

While we had AEWG-62 in the virtual platform, the AEWG in person meetings have networking and social events, which cannot be replicated in a virtual platform. Therefore, we decided not to hold another virtual meeting this year.

Best Regards,

Talks describing AE applications in any field, as well as advances in AE fundamentals, sensing, and signal processing, are invited. In keeping with the working group character of the meeting, discussion of work in process is particularly welcome.  Students may submit an extended abstract for consideration for the AEWG Student Award.

Topics will cover all the areas of acoustic emission research, development and applications, including but not limited to:
  • Wave propagation of AE source mechanisms
  • Infrastructure and health monitoring
  • AE for composites
  • Advances in AE instrumentation and sensors
  • AE for materials/structure damage mechanics
  • AE applications for large scale structural testing
  • Novel signal processing approaches
  • Material research, fracture and fatigue failure mechanisms
  • Geosciences and rock mechanics
  • Orthopedics and biomechanics
  • Manufacturing applications
  • Diagnostic techniques & procedures
  • Codes and standards development
  • AE theories, methods, validation and verification

Workshop themes:

  • Acoustic Emission instrumentation, data processing and nondestructive/structural health monitoring applications
  • Acoustic Emission for materials/structural damage monitoring and identification
  • Analytical, numerical and computational modeling as well as validation of Acoustic Emission source and wave propagation effects



53  years passed since the first meeting of Acoustic Emission Working Group (AEWG) was held in Idaho Falls, on February 8, 1968.
AEWG had its beginning in a discussion between Allen T. Green (then at Aerojet-General Corp., later at Acoustic Technology Group) and Jack Spanner (then at Battelle Northwest). Spanner arranged for a formative meeting of interested parties to be held in Alcoa, TN, on November 2, 1967.
The 12 people in attendance agreed to hold the first meeting in Idaho Falls in three months. At that time, eight others (T. Theodore Anderson, Thomas F. Drouilliard, Robert B. Engle. Robert G. Liptai, O.K. Mitchell, R. Neal Ord. Ronald E. Ringsmith and Richard K. Steele) joined to become the charter members of the AEWG.
