Analysis and identification of linear and nonlinear normal modes in vibrating systems
In the first part of this work, the free and forced oscillations of a class of strongly nonlinear, undamped, discrete oscillators, are studied. The free motions are examined by using the notion of "nonlinear normal mode," originally introduced by Rosenberg. Analytical methods for computing...
