.... The experiments are performed in a horizontal wind tunnel using silicon filaments horizontally clamped at their upstream ends. We observed, at low flow velocity, static equilibrium states. Then, above a critical value of the velocity, the filament exhibits regular oscillations in a vertical plane. The theoretical...

... during the total number of iterations of an equilibrium state. A special iteration algorithm is explained for eccentrically connected members by using a rigid arm methodology. Attention is also paid to flexible member connections so that introducing master and slave degrees of freedom are avoided...
