Abstract
The nonlinear chaotic response of a harmonically forced elastic oscillator with quadratic and cubic nonlinearities is studied. The possibility of obtaining reliable prediction of bifurcations and chaos through combined use of stability analysis of low-order approximate solutions and accurate localized point-by-point and cell mapping computer simulations is examined. Some satisfactory results are obtained for the bifurcation predictive capability and the location of regions where chaos actually occursFile in questo prodotto:
