Approximate Solution for the Duffing-Harmonic Oscillator by the Enhanced Cubication Method
The cubication and the equivalent nonlinearization methods are used to replace the original Duffing-harmonic oscillator by an approximate Duffing equation in which the coefficients for the linear and cubic terms depend on the initial oscillation amplitude. It is shown that this procedure leads to an...
