Research Interests

Professor Reddy is well-known for his research as well as for his teaching. Professor Reddy is distinctly known for his research on mechanics of composite materials and of computational methods, which deals with theoretical formulations and numerical analysis of problems in engineering. The shear deformation plate and shell theories that he developed and bear his name are well known and finite element models have been implemented into commercial software like ABAQUS, NISA, and HYPERFORM, which are accessible to engineers around the world. Professor Reddy has also contributed significantly to the modernization of our education, since his books are used as text books in courses of Mechanical, Civil and Aerospace Engineering and Mechanics. An especially strong point of Dr. Reddy’s classroom teaching is the clarity and physical insight of explanations of even the most difficult topics through relevant engineering examples, but without compromising on the mathematical rigor.

Such an eminent record of research has earned Dr. Reddy numerous national and international awards, including the Charles Russ Richards Memorial Award and the Worcester Reed Warner Medal of the American Society of Mechanical Engineers, Nathan M. Newmark Medal from the American Society of Civil Engineers; Award for Excellence in the Field of Composites and Distinguished Research Award from the American Society for Composites, the Computational Solid Mechanics award from US Association for Computational Mechanics, and the Archie Higdon Distinguished Educator Award from the American Society of Engineering Education. Dr. Reddy presented the prestigious “The 2009 Landis-Epic Lecture” at the University of Pittsburgh, and received Honorary degrees from the Technical University of Lisbon, Portugal, and Odlar Yurdu University, Baku, Azerbaijan. Recently, he was honored as an Honorary Member of the American Society of Mechanical Engineers. Dr. Reddy is one of the very few researchers in engineering around the world, who is recognized by ISI Highly Cited Researchers (with over 10,000 citations and h-index of 50).

Professor Reddy also played active roles in professional societies as the President of USACM, founding member of the General Council of IACM, Secretary of Fellows of AAM, member of the Board of Governors of SES, Chair of the Engineering Mechanics Executive Committee, among several others. He either served or currently serving on the editorial boards of a large number of journals. In addition, he served as the Editor of Applied Mechanics ReviewsMechanics of Advanced Materials and Structures, the International Journal of Computational Methods in Engineering Science and Mechanics, and the International Journal of Structural Stability and Dynamics.
