Determination of limit cycle by He's parameter-expanding method for strongly nonlinear oscillators

This paper applies He's parameter-expanding method (PEM) to determine the limit cycles of strongly nonlinear oscillators by which one iteration leads to an accurate solution. Comparison of the obtained results with those of the exact solution shows that the method is very effective and convenient and quite accurate to both linear and nonlinear physics and engineering problems.
