This research aims to develop the underlying theory and methods for             analyzing the effect of irregularities on the dynamics of nearly                periodic structures.  The research will address two main issues:  (1)           formulate a general criterion capable of predicting the occurrence of           strong localization for structural systems and, therefore, gain a               physical insight into mode localization; and, (2) investigate mode              localization from two types of nearly periodic structures--namely,              assemblies of multi-Degree-of-Freedom (DOF) component systems and one-          and two-dimensional multi-span continuous structures--and thereby               assess the damaging or beneficial effects of localization for both free         and forced responses.
