"Unified Approach for Accurate and Efficient Modeling of Composite Rotor Blade Dynamics” 

a talk by

Professor Dewey Hodges

2014 Nikolsky Lecturer for the American Helicopter Society

About the lecture
The development of a unified approach is described, which spans several decades and facilitates accurate and efficient modeling of composite helicopter rotor blades for loads, dynamics, aeroelasticity, and stress recovery. The approach achieves accuracy comparable to that of three-dimensional finite element analysis but with significant savings in computational effort. The basis for this approach is a mathematical technique called the variational asymptotic method. This paper summarizes the modeling approach and presents some of the key equations of the resulting analyses. Examples are presented that illustrate the accuracy and efficiency of the approach as implemented in the computer application Variational Asymptotic Beam Section (VABS) and appropriate beam equations, along with ample citations to published works in which these analyses are developed and/or used.
About the speaker

Prof. Hodges has been on the faculty of the School of Aerospace Engineering at Georgia Tech since the fall of 1986. His present research interests include analytical and computational structural mechanics, aeroelasticity, structural dynamics, asymptotic methods, dynamics and computational optimal control. He has presented papers and seminars at many technical conferences and universities across the United States, Western Europe, South America, and Asia. He has advised 33 PhD and 39 MS graduates. To his credit thus far he has four book chapters, five books, over 200 technical papers in refereed journals, and two U.S. Patents. In recent years his research group at Georgia Tech has been developing methods for accurate analysis and stress recovery in composite beams (including helicopter rotor blades), plates, and shells. The computer programs VABS (for composite beams) and VAPAS (for composite plates and shells) are in use around the world. These codes facilitate the accurate modeling and accurate stress recovery of internally complex structural members using generalized forms of standard reduced-order models for beams, plates, and shells. Also, the code NATASHA was developed for nonlinear aeroelasticity analysis of HALE aircraft and was selected by DARPA for use by contractors in its VULTURE program.

Prof. Hodges has received several awards in his professional career. These include his election to Fellow in four professional societies: The American Academy of Mechanics, The American Helicopter Society (AHS), The American Institute of Aeronautics and Astronautics (AIAA), and The American Society of Mechanical Engineers (ASME). In addition he has been awarded a NASA Technology Utilization Award (1975), two NASA Tech Brief Awards (1976 and 1990), a U.S. Army Commendation Medal (1977), the prestigious U.S. Army Research and Development Achievement Award (1979), the Director’s Award for Technological Achievement (1984), six Official U.S. Army Commendations (1980-1986), two SAIC Technical Paper Awards (1990 and 1998), three Sigma Xi Research Awards (1990, 1995, 2003), the Sigma Xi Sustained Research Award (2011), the AIAA Ashley Award for Aeroelasticity (2013), the AHS Alexander A. Nikolsky Honorary Lectureship (2014), and the ASME Spirit of St. Louis Medal (2015). He serves on the Editorial Boards of Journal of Mechanics of Materials and Structures, the Journal of Fluids and Structures, and the journal Nonlinear Dynamics. He also served as an Associate Editor for the AIAA Journal, as a member of the AIAA Structural Dynamics Technical Committee, multiple terms as a member of the AHS Dynamics Committee, on the Editorial Board of the International Journal of Solids and Structures, and as an associate editor of the Journal of Engineering Mechanics.
