✦ Synopsis

Non-linear modal analysis approach based on invariant manifold method proposed earlier by Shaw and Pierre (Journal of Sound and <ibration 164, 85}124) is utilized here to obtain the non-linear normal modes of a clamped}clamped beam for large amplitude displacements. The results obtained for the fundamental normal mode are compared with the corresponding reported experimental and theoretical studies. The e!ects of modal coupling are examined in greater detail. The limitation of the present method for analyzing non-linear behavior is highlighted.

For a strongly non-linear multi-degree-of-freedom system, in general, one cannot consider one mode at a time as in linear modal analysis. In the absence of external excitation, the natural vibration often involves more than one mode at a time resulting in quasi-periodic or multi-periodic (toroidal)
