The benefits and challenges of NDE 4.0 and the role AE will play
Dr. Johannes Vrana
Vrana NDE Consulting & Solutions (Germany)
Dr. Johannes Vrana, born in 1978, studied physics at the Technical University of Munich, Germany with a focus on quantum computers and completed his PhD in 2008 at the University of Saarland on thermographic testing. He then worked for Siemens Power and Gas in Orlando, USA as well as in Berlin and Munich, Germany and was responsible for all supplier related NDE questions and was Chairman of the Siemens NDE Council. In addition to world-wide harmonization of NDT specifications and the introduction of statistical tools, he was responsible for the development of automated NDT and SAFT. In 2015 he received an Honorable Mention for ingenuity at the U.S. Excellence Awards and in 2016 he received the 4th price for Ingenuity at the Werner von Siemens Awards. In 2015 he started his own company “Vrana GmbH” in Rimsting, Germany which specializes in NDE consulting and solutions, R&D, and software development. Moreover, he is chairman of the ICNDT (International Committee for NDT) Specialist International Group “NDE 4.0“, of the ASNT (American Society for NDT) German Section, and of the DGZfP (German Society for NDT) subcommittees “Interfaces and Documentation for NDE 4.0“ and “Automated Ultrasonic Testing “. In 2019 he was awarded with the DGZfP application award for the implementation of SAFT into serial production of large rotor forgings.
A glimpse of forty-nine years in acoustic emission
Dr. Marvin Hamstad
Professor Emeritus, University of Denver (US)
Dr. Marvin Hamstad (Ph.D. ME/Solid Mechanics, University of California, Berkeley) has been continuously involved in acoustic emission research and applications since 1971. This AE work ranged from nondestructive testing applications to materials characterization. He has worked in the field of composite materials since the 1970s. His various research efforts have resulted in more than 135 papers. From 1971-84, he was at Lawrence Livermore National Laboratory. From 1984-2010, Dr. Hamstad was Professor of Engineering at the University of Denver. He is currently Professor Emeritus. Since 1992, Dr. Hamstad has had positions working on AE at the National Institute of Standards and Technology, Boulder, CO. He was chairman of the Committee on Acoustic Emission from Reinforced Plastics for 16 years, where he initiated the AECM international symposiums (1983-98). Dr. Hamstad was an associate editor of J. Structural Health Monitoring, and currently serves as a co-editor of the JAE.
Acoustic emission for multi-scale assessment of degradation in existing structures
Dr. Els Verstrynge
Assistant Professor, Catholic University of Leuven (Belgium)
Dr. Els Verstrynge is Assistant Professor at the Catholic University of Leuven, Belgium. She has a dual background in structural and architectural engineering. Her research interests include multi-scale numerical and experimental analysis of degradation mechanisms in brittle construction materials, historical masonry and RC structures, advanced NDT and integrated monitoring, such as acoustic emission sensing. She has spent research stays at the Technical University of Delft (2009), the University of Minho (2012) and Stanford University (2016). She currently supervises a group of five PhDs and postdocs, with a research focus on “Multi‐scale assessment of damage and degradation in existing structures”.
Acoustic emission of composites - about the when, where and what and the residual capacity
Dr. Markus Sause
University of Augsburg (Germany)
Dr. habil. Markus Sause studied Physics at the University of Augsburg and earned his doctoral degree in 2010 in Experimental Physics at the same place. In 2015, he succeeded with his Habilitation in Experimental Physics. Since 2016, he is Professor at University of Augsburg at the Institute for Materials Resource Management. In 2019, he received the “Science Award” from the German NDT society (DGZfP) for his outstanding contributions to the field of nondestructive testing. Since 2014, he is member of the EWGAE executive committee and active in several other committees dedicated to the testing and analysis of fiber-reinforced materials. His research interest span the mechanics of fiber reinforced composites, their destructive and non-destructive testing as well as numerical methods to interpret the material behavior resulting in >100 publications. A special focus is given to bridge the gap between destructive testing approaches and non-destructive inspection to perform in-situ analysis of material failure.
