The nonlinear dynamics of circular cylindrical shells under combined axial static and periodic forces are
experimentally investigated. The goal is to study the dynamic scenario and to analyze non-linear regimes. The
linear behavior under static preload is analyzed by means of the usual modal testing techniques. The complex
dynamics arising when a periodic axial load excites the first axisymmetric mode are analyzed by means of
amplitude frequency diagrams, waterfall spectrum diagrams, bifurcation diagrams of Poincare maps, time
histories, spectra, phase portraits.
