Q. Bi et Hh. Dai, Analysis of non-linear dynamics and bifurcations of a shallow arch subjected to periodic excitation with internal resonance, J SOUND VIB, 233(4), 2000, pp. 557-571
In this paper, the dynamical behavior of a shallow arch subjected to period
ic excitation with internal resonance is explored in detail. The parametric
plane is then divided into different types of regions by the transition bo
undaries according to the types of the steady state solutions. A time-integ
ration scheme is used to find the numerical solutions in these regions, whi
ch agree with the analytic results. Finally, numerical simulation is also a
pplied 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.
