Effect of the thickness to length ratio on the frequency ratio of nanobeams and nanoplates

open access: yesJournal of Theoretical and Applied Mechanics, 2019
This communication presents the effect of thickness on the frequency ratio of nanobeams and nanoplates using Eringen's nonlocal theory. Although there exist numerous works regarding the effects of thickness and small scale on the frequency ratio of nanobeams and nanoplates, none has captured and reported the true effects.
