Free vibration of axially loaded zigzag and armchair nanobeams using doublet mechanics

Based on doublet mechanics theory and various beam theories, this paper presents free vibration of axially loaded zigzag armchair nanobeams. A two-noded higher order element is used to solve the problems nanobeams with boundary conditions. The verification studies in terms fundamental frequencies buckling loads are performed by comparing results present model Molecular Dynamic Simulations, Doublet Mechanics, Eringen’s nonlocal theory. effects material length scale parameter, slenderness ratio, nanotube conditions investigated details. Softening behavior detected for Having stiffer lead effect parameter be observed more prominently.
