Use of ultrasonic and electromagnetic waves is continuously increasing for nondestructive evaluation (NDE) and structural health monitoring (SHM). guided waves have become popular for NDE/SHM applications because they can propagate long distances and reach regions that are difficult to access. Recent advances in NDE and SHM using ultrasonic guided waves and electromagnetic waves will be discussed. Wave propagation in complex structures are difficult to model analytically or numerically by the popular finite element method. A mesh-free technique called the distributed point source method has been developed for solving such problems and will be presented in addition to the experimental results.
Tribikram Kundu of University of Arizona received his PhD from UCLA. His research is on NDE/SHM. He has supervised 31 PhD and 21 MS students, published 280 technical papers, 140 in journals, 2 textbooks, and edited 5 research monographs. He is a fellow of ASME, ASCE and SPIE. He was awarded the Humboldt Research Prize (the Senior Scientist Award) from Germany in 2003 and Humboldt Fellowship earlier. He is recipient of the NDE Lifetime Achievement Award from SPIE and Structural Health Monitoring Person of the Year from the SHM Journal. He has several invited professorships from Europe and Asia.
