Abstract
The stability properties of a periodically loaded non-linear dynamic system are investigated and special attention is given to damping effects. Advant age is taken of the Floquet theory and the FE-approach is applied to a hing ed beam where the damping is described by a standard material model and whe re even damping effects at the hinges are considered. Comparisons are made with experimental results. (C) 2001 Academic Press.
