Abstract:Use ofultrasonic waves is continuously increasing for nondestructive evaluation (NDE)and structural health monitoring (SHM) in civil, mechanical and aerospaceengineering applications. My international research collaborations on linearand nonlinear ultrasonic techniques with different universities and institutesin Asia, Europe and America will be discussed in this presentation. Between bulk waves and guided waves the latter has become more popular forNDE/SHM applications because the guided waves can propagate long distances andreach regions that are difficult to access otherwise. Recent advances inresearch related to NDE and SHM of various engineering structures made of metaland polymer composite plates, concrete and cement composites will be discussedwith experimental results. To analyze the experimental results often oneneeds to understand the mechanics of wave propagation in complex problemgeometries. Structures with internal defects are difficult to solveanalytically or numerically by the popular finite element method because thesize of the individual elements and time steps required for such analysesbecome prohibitively small at high frequencies. An alternative mesh-freetechnique called the distributed point source method (DPSM) has been developedfor solving such problems and will be presented along with the experimental results.
Brief Bio:ProfessorTribikram Kundu received his bachelor degree in Mechanical Engineering from IITKharagpur in 1979; there he was the winner of thePresidentof IndiaGoldMedal (PGM) for ranking first among all graduatingengineers. After completing his MS and PhD at the University ofCalifornia in Los Angeles and winning the outstanding graduate student award inUCLA Engineering college he joined the University of Arizona (UA) as anAssistant Professor in 1983, and was promoted to Full Professor in 1994. He wasdistinguished as a Faculty Fellow for research in the UA College of Engineeringin 2012.
