摘要

Non-linear vibrational characteristics of a nano-beam were studied taking the non-local effect into account. The physical model was built based on the continue body theory and the effect of axial elongation for the nano-beam. The dynamic equations were derived based on the non-local effect. The natural frequencies were obtained and the principal resonance was studied considering non-local effect and axial nonlinear elongation. The numerical results showed that the non-local effect has effects on both the natural frequencies and the relationship between frequency and amplitude.
