Abstract
Purpose
The purpose of this paper is to validate the variational iteration method (VIM) is suitable for various nonlinear equations.
Design/methodology/approach
The He’s VIM is applied to solve nonlinear equation which is derived from actual engineering problem. The result was compared with other method.
Findings
The result obtained from VIM shows good agreement with Xu’s result which provide a solid evidence that VIM is convenient and effective for solving nonlinear equation in the engineering.
Originality/value
The VIM can be extended to many academic and engineering fields for nonlinear equations solving.
