In this paper. He's variational approach is applied to the strongly nonlinear oscillators with high nonlinearity. Some examples are given to illustrate the effectiveness and convenience of this method. Comparison with the exact solutions is also made, revealing that the present method leads to accurate solutions. (C) 2009 Elsevier Ltd. All rights reserved.
