A Q&A session led by Section Educational Director Hashem N. Al-Nasser and a raffle drawing followed the presentation. Southern Africa J O H A N N E S B U R G , S O U T H A F R I C A The Southern Africa Section held a very successful technical meeting via an online platform on 20 April. Jan-Albert Viljoen of Gammatec and Christian Smith of Interactive Aerial Inc. presented on “Zenith – Confined Space Inspection Camera System.” Regional Director, Region 18, Mark A. Ormrod was in attendance. The 18 attendees enjoyed a lively debate on all aspects of this new technology. Southwestern Ontario M I S S I S S A U G A , O N T A R I O , C A N A D A The Southwestern Ontario Section held an executive virtual meeting on 16 February with six members in attendance. Susquehanna Valley Y O R K , P E N N S Y L V A N I A On 26 March, the Susquehanna Valley Section held a virtual “Lunch and Learn” hosted by the Pennsylvania State University attended by 26 individuals. The Section was graced by the presentations of two students performing research in the Penn State Ultrasonic Lab under the supervision of Parisa Shokouhi, Ph.D., associate professor of engineering science and mechanics and editor-in-chief of Research in Nondestructive Evaluation. Evan Bozek and Colin Williams are both seniors at Penn State enrolled in the Integrated Undergraduate-Graduate Program. During the course of their under- graduate studies, they have been performing research in the area of nonlinear ultrasonics. Bozek began the meeting by presenting on nonlinear resonance ultra- sonic spectroscopy (NRUS) for additive manufactured (AM) parts. His presentation demonstrated that it is a viable solution for AM part qualification by demonstrating the correlation between NRUS test parame- ters and fatigue life. Bozek further pointed out the need to move from a traditional coupled testing setup to an air-coupled approach using air-coupled excitation and laser for reception. This would reduce the measurement uncertainty. Williams presented his work on nonlinear ultrasonic testing for predicting fracture toughness of steel samples during the second half of the meeting. He began by explaining the application and the justi- fication for a need to develop such a test method. Williams’s work focused on relating bulk wave and surface wave nonlinearities to absorbed energies in order to ultimately predict fracture toughness. Williams highlighted a need for numerical modeling and additional materials characterization during future research he plans to conduct. It is clear the future of nondestructive examination is in good hands after hearing the presentations from these two bright young professionals. The Section would like to further extend its gratitude to Bozek and Williams for their excellent presentations.
