Abstract:
Use of ultrasonic and electromagnetic waves (such as THz radiation) is continuously increasing for nondestructive evaluation (NDE) and structural health monitoring (SHM) in aerospace, civil, electrical, mechanical and biomedical engineering applications. Between bulk waves and guided waves the latter has become more popular for NDE/SHM applications because the guided waves can propagate long distances and reach regions that are difficult to access otherwise. Recent advances in research related to NDE and SHM of various engineering and biological materials and structures using ultrasonic guided waves and electromagnetic waves will be discussed with experimental results. To analyze the experimental results often one needs to understand the mechanics of wave propagation in complex problem geometries. Structures with internal defects are difficult to solve analytically or numerically by the popular finite element method because the size of the individual elements and time steps required become prohibitively small at high frequencies. An alternative mesh-free technique called the distributed point source method (DPSM) has been developed for solving such problems and will be presented along with the experimental results.
Brief Bio: Professor Tribikram Kundu received his bachelor degree in Mechanical Engineering from IIT Kharagpur in 1979; there he was the winner of the President of India Gold Medal (PGM) for ranking first among all graduating engineers. He went to UCLA for graduate study. After completing MS and PhD and winning the outstanding graduate student award from UCLA he joined the University of Arizona as an Assistant Professor in 1983, and was promoted to Full Professor in 1994. He was distinguished as a Faculty Fellow for research in the College of Engineering in 2012. To date he has supervised 39 PhD (34 at UA) and 28 MS (27 at UA) students, published 9 books, 18 book chapters and 333 technical papers; 168 of those in refereed scientific journals. According to Google Scholar his h-index is 42, with 6352 total citations. He won the Humboldt Research Prize (Senior Scientist Award) and Humboldt Fellowship awards from Germany, 2012 NDE Life Time Achievement Award from SPIE (the International Society for Optics and Photonics), 2015 Research Award for Sustained Excellence from ASNT (American Society for Nondestructive Testing), 2015 Lifetime Achievement Award and 2008 Person of the Year Award from the Structural Health Monitoring journal. He received a number of Invited Professorships from France, Germany, Sweden, Switzerland, Spain, South Korea, Singapore, Poland, China, Japan, Italy and India. He is Fellow of 5 professional societies - ASME, ASCE, SPIE, ASNT and ASA. He is the founding Editor-in-Chief of the ASME Journal of Nondestructive Evaluation, Diagnostics and Prognostics of Engineering Systems and Associate Editor of Ultrasonics journal. He served as Associate Editor of 3 other journals.
