Solving strongly nonlinear oscillation problem of conservative system by using linearization and interpolation perturbation Methods |
|
| Abstract: | In this paper, using the linearization and the interpolation methods, the author seeks to solve a class of problems of the strongly nonlinear oscillations of the conservative systems. The accuracy of this method is quite well and is better than that of the improved L-P method. |
| Keywords: | interpolation perturbation method linearization perturbation method strong nonlinearity oscillation conservative system method of weighted residuals (MWR) |
