Flexural-Torsional Flutter and Buckling of Braced Foil Beams under a Follower Force

Figure 4

Linear stability diagrams of the damped foil beam in the -plane: (a) case study I; (b) case study II. Black curves: damped beam. Gray curves: undamped beam. : undamped Hopf locus, : Hopf locus for lumped dashpot at the tip, : Hopf locus for distributed internal and external damping, : Hopf locus for all the damping forms acting simultaneously, : divergence locus, and DZ: double-zero bifurcation point.
