Axial vibration of carbon nanotube heterojunctions using nonlocal elasticity

In the present study, axial vibration of carbon nanotube heterojunctions is studied using nonlocal rod theory. The nonlocal constitutive equations of Eringen are used in the formulations. The carbon nanotubes with different lengths, chirality and diameters are considered in the heterojunctions. Effect of nonlocality, length of the carbon nanotubes and lengths of each segment are investigated in detail for each considered problem. It is obtained that, by joining carbon nanotubes good vibrational properties are obtained by suitable selection of parameters.
