Nonlinear normal modes of buckled beams: Three-to-one and one-to-one internal resonances
The authors use the method of multiple scales to study nonlinear normal modes for a first-mode buckled beam, in the case of one-to-one and three-to-one internal resonances. In particular it is found that the buckled beam possesses rich nonlinear behavior even in the case without damping or external resonances.
