..., which is initiated by means of the harmonic forcing, and dry friction are accounted for. The presented procedure relies on the computation of the system's nonlinear normal modes (NNM) and their analysis through the application of an energy principle derived from the Melnikov function. The dynamic...

... geometrical nonlinearity nonlinear normal modes bifurcation localization The study considers both free and forced vibrations of structures with a cyclic symmetry under geometrical nonlinearity. This class of systems appears in the model of a bladed disk or a space antenna ( 1 2 ). It leads...
