What is Non-linear Modal Analysis of Structural Systems Featuring Internal Resonances about?
The superposition theorem is the cornerstone of linear system theory, which enables the study of the dynamic behavior of linear systems, both analytically and numerically. It is precisely this theorem which, by allowing modal analysis, capitalizes on the concept of normal modes of motions and renders them so important. By contrast, it is also precisely such a manner of recombining general motions from individual modal co-ordinates that is missing for non-linear dynamic systems (in particular, structural systems, on which this line of work is focused). Consequently, although the concept of non-linear normal modes of vibrations is well established for general, vibratory, non-linear, structural systems (see references [1][2][3][4][5][6][7]), their use in structural dynamics is restricted to very particular motions; namely, those involving a single mode response. Indeed, as superposition of individual modal responses cannot be performed, general motions of a non-linear structural system cannot usually be easily determined (except possibly for systems with similar non-linear modes). Such motions are typically handled by projecting the non-linear system on to a basis consisting of the mo
