Localization phenomena in structural dynamics
The author gives a survey of vibration localization phenomena in structural dynamics. The review covers the more common and relevant cases where the mode localization and vibration confinement can occur in engineering structures. Presented examples include periodic or nearly periodic multi-span beams, multi-bay trusses, large space structures, and almost periodic structures with circular symmetry. The author discusses analytical and numerical methods for analyzing and predicting localization in various systems, and shows that this problem can be formulated as a problem of stability theory. Making use of this fact, the author gives some new definitions of mode localization. The possibility of stabilizing certain nonconservative fluid-structure systems is demonstrated, and it is shown that the results from localization theory and the associated stability theory can be applied to the vibration control by triggering vibration confinement by various means.
