Abstract

An analytical procedure is presented for modeling the behavior of rotating blades with integrated piezoelectric devices. The equation of motion and associated boundary conditions are derived for the vibrations of piezoelectrically actuated rotating beams/blades. The effects, so-called 'centrifugal-softening and centrifugal-stiffing,' of the displacement-dependent centrifugal forces are investigated in the present study.
