Variational iteration algorithm-II for solving the system of third order non-linear integro-differential equations

  Variational iteration method is widely used for solving nonlinear, integro-differential equations. Through careful investigation of the iteration formulas of the earlier variational iteration algorithm (VIM), we find unnecessary repeated calculations in each iteration. To overcome this shortcoming, the variational iteration algorithm-II (He et al., 2010) will be used in this paper to solve the system of non...

Finite element modeling and analysis of zigzag and armchair type single wall carbon nanotube

  A carbon nanotube (CNT) possesses superior mechanical, electrical and optical properties. The stiffness and flexibility is much higher than those of conventional fibers. Various investigators have carried out various experiments as well as theoretical analysis which show that the carbon nanotubes possess superior mechanical properties. The model development in this work is based on the assumption that carbon...
