Texas A&M University US

Dr. Reddy is a Distinguished Professor, Regents’ Professor, and inaugural holder of the Oscar S. Wyatt Endowed Chair in Mechanical Engineering at Texas A&M University. Dr. Reddy earned a Ph.D. in Engineering Mechanics in 1974 from University of Alabama. He worked as a Post-Doctoral Fellow in Texas Institute for Computational Mechanics, the University of Texas at Austin, a Research Scientist for Lockheed Missiles and Space Company in Huntsville, and taught at the University of Oklahoma, Virginia Tech, and Texas A&M University.

Dr. Reddy’s research has involved the development of refined theories and finite element analysis of problems in composite structures, fluid dynamics, and biology and medicine. His shear deformation plate and shell finite element models have been implemented into commercial finite element computer programs like ABAQUS, NISA, and HyperForm. He is the author of over 500 journal publications and 18 textbooks with nearly 40,000 citations and h-index of 77 (Google search).


Project: Structural theories used to determine their response has been historically based on local elasticity equations. Molecular dynamics and lattice dynamics studies have shown that the stress at a point may depend on strains at the point as well as strain within the vicinity of the point. Recently, the Reddy and his colleagues have developed modified couple stress theories, gradient elasticity theory, and modified couple stress theory to bring out microstructure-dependent size effects. The proposed research has the objective of unifying these ideas and developing structural theories that contain microstructural length scales, and ascertain their influence on bending and vibration characteristic of nanostructures in the form of beams, plates, and shells. These theories will used to develop the governing equations of beams, plates, and shells. The proposed research will also develop finite element models to investigate the influence of various material length scales in structures with hard but small inclusions in soft matrix materials.
