LONGITUDINAL FORCED VIBRATION ANALYSIS OF POROUS A NANOROD

Öz

In this paper, longitudinal vibration responses of a nanorod subjected to harmonic external load are investigated with porosity based on Nonlocal Elasticity theory. The governing equation of the problem is solved by analytically. Frequency equations and the forced vibration displacements are obtained exactly. In the numerical examples, effects of the nonlocal, dynamic, geometry and porosity parameters on forced vibration responses of the nanorod are investigated.
