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.
