- Abstract
In this article, a kind of analytical method called He’s variational iteration method (VIM) have been used to obtain the
analytical solution of two-dimensional nonlinear wave equation. In this method, general Lagrange multiplier is
introduced to construct correction functions for the problems. The multiplier can identify optimally via the variational
theory. The results compare with those of exact solutions and homotopy perturbation method. A clear conclusion can
be drawn from the numerical results and the proposed method provides excellent approximations to the solution of this
kind of nonlinear wave phenomenon in terms of simplicity and accuracy. Thus, it can be easily extended to other
nonlinear wave phenomena finding wide application.
