โœฆ Synopsis

In this paper, the dynamical behavior of a shallow arch subjected to periodic excitation with internal resonance is explored in detail. The parametric plane is then divided into di!erent types of regions by the transition boundaries according to the types of the steady state solutions. A time-integration scheme is used to "nd the numerical solutions in these regions, which agree with the analytic results. Finally, numerical simulation is also applied to obtain double-period cascading bifurcations leading to chaos and the steady state period-3 solution is shown in the chaos region in the end.

A geometrically non-linear model of the rotating shaft is introduced, which includes KaH rman non-linearity, non-linear curvature e!ects, large displacements and rotations as well as gyroscopic e!ects. Through applying Timoshenko-type assumptions, the shear e!ects are also included in the model. Con
