Abstract: Use of ultrasonic waves is continuously increasing for nondestructive evaluation (NDE) and structural health monitoring (SHM) in civil, mechanical and aerospace engineering applications. My international research collaborations on linear and nonlinear ultrasonic techniques with different universities and institutes in Asia, Europe and America will be discussed in this presentation.  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 structures made of metal and polymer composite plates, concrete and cement composites 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 for such analyses 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. After completing his MS and PhD at the University of California in Los Angeles and winning the outstanding graduate student award in UCLA Engineering college he joined the University of Arizona (UA) 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 UA College of Engineering in 2012. To date he has supervised 39 PhD and 28 MS students, published 9 books, 18 book chapters and 345 technical papers; 175 of those in refereed scientific journals. According to Google Scholar his h-index is 45, with over 7000 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 Italy, India, China and Japan. 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. Earlier he served as Associate Editor of 3 other journals.
