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.encircular cylindrical shellexperimentschaosNonlinear Dynamics of Pre-Compressed Circular Cylindrical Shell Under Axial Harmonic Load: ExperimentsArticle
