ABSTRACT In the previous decades, many numerical and experimental investigations on the capabilities of periodic structures for vibration attenuation and localization were performed and proved those capabilities for different simple structures. Earlier investigation of such phenomenon in periodic plates was not promising due to different factors. In this research, experimental and numerical investigations of the vibration response of different periodic plates are investigated to examine similar behavior of periodic plates. Three different periodic configurations were tested under ‘almost’ free support boundary conditions. This work is an important over that performed by Hull [9]. Milled plates are used to avoid the effect of the adhesive material in damping which was used [3]. The experiments involved the excitation from one corner of the square plate and measuring the response at the three other corners. The results were compared to that of a similar size plain plate. The results indicated the reduction of the response of the periodic plates, which have overall less weight, by ratios that may exceed 10 db in different frequency bands. The results of this work, verified by experiments, encourage more investigation on the localization capabilities of those plates as well as the preparation of numerical models that may predict those results in a more accurate fashion.
