Abstract

The impacts of imperfections on the mode shapes and general response of a simple 'near'-periodic structure were investigated. It was determined that imperfections which augment the stiffness have a more considerable effect on the higher mode shapes than imperfections which minimize the stiffness. It was also observed that for a structure with randomly distributed parameters, the lower modes are inclined to localize at the bay with the lowest frequencies, while the higher modes tend to localize at bays with the highest frequencies. In the case of a 'near'-periodic structure, the response is greatly localized in the bay at which the initial condition is not zero.
