Dewey H. Hodges is a professor of aerospace engineering at the Georgia Institute of Technology. He has been the principal or co-principal investigator for more than 45 externally sponsored research projects in the fields of aeroelasticity, structural mechanics, rotorcraft dynamics, finite element analysis, and computational optimal control. In recent years, his research group has been developing methods for accurate analysis of and stress recovery in composite beams, including helicopter and wind turbine rotor blades, plates and shells. The computer programs VABS (for composite beams) and VAPA...
