| Abstract: | Experiments on the chaotic motions of a clamped-sliding buckled beam to a harmonic axial load are presented. Two types of resonance are studied, fundamental and principal parametric resonance. The types of chaos found in the experiments are varied by different excitation frequencies and excitation amplitudes and damping levels. Long-time histories,spectra of the response, and poincare maps are presented. |

| Keywords: | chaotic motion parametric nonlinear oscillator poincare map |
