Dr. Subhendu Datta has been a Professor of Mechanical Engineering at the University of Colorado at Boulder since 1974. He received a Bachelor of Science degree in 1954 with first class honors in Mathematics from the Presidency College, Calcutta; Master of Science degree in Applied Mathematics from the Calcutta University; Ph. D. degree in 1962 in Applied Mathematics from the Jadavpur University, Calcutta. He was a Lecturer at the Jadavpur University, Calcutta, from 1957-62; Research Lecturer at the Mathematics Research Center, University of Wisconsin, Madison, 1962-63; Post-Doctoral fellow, Department of Mathematics, Rensselaer Polytechnic Institute, Troy, NY, 1963-64; Visiting Assistant Professor, University of Colorado, Boulder, 1964-65; Assistant professor, Indian Institute of Technology, Kanpur, India, 1965-67; Assistant Professor, University of Manitoba, Winnipeg, Canada, 1967-68; Assistant and Associate Professor of Mechanical Engineering, University of Colorado at Boulder, 1968-74. He has had Visiting Professor appointments at the Punjab University, Chandigarh, India, Calcutta University, National University of Mexico, Technical University of Vienna, and Chalmers University of Technology in Sweden. He was at the Division of Basic Energy Sciences, DOE, as an IPA engineer from 1993-94.

Dr. Datta received Fulbright Scholarships in 1962 and 1986; was recipient of Faculty Fellowships from the University of Colorado at Boulder, in 1972 and 1986; received NSF International Awards for visiting India, Ireland, and Sweden.

Dr. Datta is a Fellow of the American Society of Mechanical Engineers and the American Academy of Mechanics. He is an Associate Editor of the Journal of Engineering Materials and Technology, Composites Engineering, and the Applied Mechanics Reviews.

Dr. Datta's research deals with analytical and numerical modeling of wave propagation and scattering in solid media. The modeling has included ultrasonic techniques for material characterization and nondestructive evaluation, elastic guided waves in layered, composite, and anisotropic plates and cylinders, and waves in thin layers and coatings. His current projects include thermomechanical properties and behavior of superconducting tapes, ultrasonic evaluation of weldments and gas pipelines, and residual stress effects.

Publications

Dr. Datta has published over 200 papers in peer reviewed journals and conference proceedings and has edited the Proceedings of the US National Congress of Applied Mechanics, 1974, Proceedings of the IUTAM Symposium on Elastic Waves and Ultrasonic Nondestructive Evaluation, 1989, and four ASME symposium volumes.
