Symmetry Approach to Extension of Flutter Boundaries via Mistuning
(American Institute of Aeronautics and Astronautics, 1998-05)
A general framework is presented for analyzing and optimizing stability increases resulting from mistuning. The framework given is model independent and is based primarily on symmetry arguments. Difficult practical issues ...
Solving for Mistuned Forced Response by Symmetry
(American Institute of Aeronautics and Astronautics, 1999-03)
The introduction of mistuning in jet-engine bladed disks can lead to large changes in stability and forced response. Even small random mistuning (within the bounds of manufacturing tolerance) can lead to unacceptable ...
