Abstract:

A flutter analysis procedure for nonlinear systems is proposed as an alternative to timewise integration methods. It is based on an energy method due to J. Roorda and S. Nemat-Nasser and shows promise of being a practical procedure provided the number of parameters can be minimised by the representation of the flutter system by an equivalent condensed two degree of freedom system in the neighbourhood fo the critical condition. The relationship to the simpler method put forward by R.F. Taylor et alia is considered. Author
