Wang, Shuqiang; He, Jihuan
Nonlinear oscillator with discontinuity by parameter-expansion method. (English)
[J] Chaos Solitons Fractals 35, No. 4, 688-691 (2008). ISSN 0960-0779

Summary: The parameter-expansion method is applied to a nonlinear oscillator with discontinuity. One iteration is sufficient to obtain a highly accurate solution, which is valid for the whole solution domain. Comparison of the obtained solution with the exact one shows that the method is very effective and convenient.
