...J. Tang, Assistant Professor,; K. W. Wang, Diefenderfer Chaired Professor in Mechanical Engineering, Fellow ASME It is known that, when the mechanical coupling between the substructures is weak, small imperfections in a periodic structure can induce vibration localization. This phenomenon could...

Instead of considering the dynamics of a single substructure alone, an essentially different technique named as wavenumber-harmonic method for the analysis of periodic structures is presented. The method involves the use of Fourier transform, then the associated wavenumber response...
