Abstract
Thin structures like shells, plates and slender beams are known to behave geometrically nonlinear, when excited to large enough oscillation amplitudes. Therefore, their experimental characterization is challenging. Typical nonlinear phenomena, such as fold bifurcations, may occur that are not covered by established identification methods. Experimental continuation is a method that, in recent studies, has been proven to be very successful for nonparametric identification of vibrating structures with local nonlinearities. In the present paper, this method is applied to a structure with distributed nonlinearity, which is a slender clamped-clamped beam. Unstable oscillation regimes, that exist between the bifurcation points are stabilized by a velocity feedback. Frequency response and backbone curves are then traced by a pseudo-arclength continuation algorithm, while the excitation force is kept harmonic by deliberate manipulation of the harmonic components.
