Classes taught by Dr. Hanagud

During his tenure at Georgia Tech, Dr. Hanagud has taught graduate courses on structural dynamics, structural stability, theory of elasticity, aeroelasticity, energy methods and finite element methods. Dr. Hanagud has taught all undergraduate courses in structural analysis. He has also taught courses on system dynamics, vibration and flutter.

New Courses Developed

Structural Dynamic System Identification

This is a graduate course taught in the School of Aerospace Engineering, Georgia Tech. The course introduces students to develop both modal models and configuration space models for structural dynamic systems by using experimental measurements. The course includes both analysis and experimental identification of selected structural systems.

Crashworthy Design of Aircraft and Rotorcraft

This is a senior level undergraduate course at Georgia Tech. The contents of the course includes crash dynamics, crash analysis, human tolerance to dynamic loads, tools available for crashworthy design of aircraft and rotorcraft, analysis of a crashworthy design to validate the design limits.

Applied Nonlinear Structural Dynamics

This course is a graduate course that is taught in the School of Aerospace Engineering at Georgia Tech. This course starts with perturbation methods like the Lindtedt-Poncare method, method of averaging and multiple scale methods. the, concepts of bifurcations, Floquet theory, Poincare maps and the concepts of stability are introduced. This is the followed by a study of chaos. Different mechanisms of transition to chaos are studied including intermittency routes, quasi-periodic routes and Melnikov's theory. Then, the control of nonlinear vibrations including a control of chaotic vibration is discussed. The course ends with a discussion of thermodynamics of chaotic vibrations.

Smart Structure Technology- Vibration Control

This is a graduate course that is taught in the School of Aerospace Engineering at Georgia Tech. This course introduces the concept smart structures based on different smart materials and associated actuators. Then the problem of vibration control by the use of smart structure technology is discussed. This includes the design of actuators, selection of sensors, placement of sensors and actuators and design of controllers. In the next phase of the course, method of applying this theory to selected simple practical structural systems. The designed systems are then implemented on selected laboratory systems and implemented by using digital signal processing, matlab based soft ware and soft ware developed by Dr. Hanagud and his students.

Other Courses Taught Since 1963

Other educational contributions include graduate courses taught by Dr. Hanagud at the University of Santa Clara, California during 1964-70. Since 1970, Dr. Hanagud is teaching both graduate and undergraduate courses during the years 1970 to the present time. Georgia Tech graduates on the average 40 to 50 Bachelor's degree candidates in the School of Aerospace Engineering. Dr. Hanagud has also advised approximately 45 M.S. (AE) students. The list of students that Dr. Hanagud has advised is listed here . Since 1974, Dr. Hanagud has graduated approximately one Ph.D. graduate per year. This is comparable to the figures at Department of Aeronautics and Astronautics at Stanford University. It is to be noted that faculty in the Department of Aeronautics and Astronautics at Stanford University do not have undergraduate teaching responsibilities. At Georgia Tech, Dr. Hanagud teaches both graduate and undergraduate courses. In leading universities, with both graduate and undergraduate teaching, the average is usually 0.4 Ph.D. students graduated per year.
