RISThe Effects of Connecting Region Length on the Natural Frequencies of Straight and Non-straight Hetero-junction Carbon Nanotubes
In the present study, the vibrational properties of straight and non-straight hetero-junction carbon nanotubes (HJCNTs) are investigated. The molecular mechanics technique in combination with the finite element method is applied to obtain the first...
Free vibration analysis of dissimilar connected CNTs with atomic imperfections and different locations of connecting region
In this paper, the vibrational characteristics of hetero-junction carbon nanotubes (HJCNTs) are investigated using the well-known molecular mechanics approach. The paper contains two main novel parts. In the first part, the influence of connecting...
Axial vibration of hetero-junction CNTs mass nanosensors by considering the effects of small scale and connecting region: An analytical solution
This paper aims to introduce a new nonlocal rod model for studying axial vibrations of hetero-junction CNTs (HJCNTs). The proposed model takes the connecting region of HJCNTs into account and is identically applicable to ...
Application of hetero junction CNTs as mass nanosensor using nonlocal strain gradient theory: An analytical solution
This paper aims to propose an analytical solution for dynamic analysis of the hetero junction carbon nanotubes (HJCNTs)-based mass nanosensors using a nonlocal strain gradient Timoshenko beam model. To have a more precise nanosensor, it is necessary...
Lateral vibrations of embedded hetero-junction carbon nanotubes based on the nonlocal strain gradient theory: Analytical and differential quadrature element (DQE) methods
In the current paper, lateral vibrations of embedded hetero-junction carbon nanotubes (HJCNTs) are investigated. HJCNT and its surrounding medium are idealized as two different connected nonlocal strain gradient Rayleigh beams and a two...
