Abstract
In this paper, we describe the application of the elliptic balance method (EBM) to obtain a general solution of the forced, damped Duffing equation by assuming that the modulus of the Jacobian elliptic functions are slowly varying as a function of time. From this solution, the maximum transient and steady-state amplitudes will be determined for large nonlinearities and positive damping. The amplitude–time response curves obtained from our elliptic balance approximate solution are in good agreement with those obtained from the numerical integration solution over the selected time interval.
