Abstract :
[en] Nonlinear normal modes (NNMs) are often used for the prediction of the backbone of resonance peaks in nonlinear frequency response functions. However, in principle, NNMs require multi-point, multi-harmonic external forcing for their practical realization. The present study proposes a new NNM definition termed phase resonance nonlinear modes. The definition is based on virtual, mono-point, mono-harmonic external forcing proportional to a specific harmonic of the velocity of the forced degree of freedom. Depending on the chosen harmonic, fundamental, superharmonic and subharmonic resonances can be characterized.
