Non-linear normal modes in dynamics - discrete systems

Result description

The aim of the review paper is to inform about main features of Non-Linear Normal Modesn(NNM) as a powerful tool for investigation of multi-degree of freedom (MDOF) dynamic systems.nIn particular, it is shown how this concept can be used to investigateforced resonances of non-linearnsymmetric systems including non-linear localization of vibrational energy. NNMs can provide a valuablentool for understanding essentially non-linear dynamic phenomena having no counterparts in linearntheory and which do not enable analysis using linearized procedures. Discrete MDOF systems are considerednin this study. A couple of possible approaches are outlined together with some demonstrationsnof numerical results.
