Enhanced He’s frequency-amplitude formulation for nonlinear oscillators

Enhanced He’s frequency-amplitude formulation for nonlinear oscillators

In this article, a trial residual Jacobi elliptic weighted function is introduced to obtain the frequency-amplitude expression of nonlinear oscillators using He’s formulation. Simulation results show an improvement in the accuracy of the frequency values when compare to numerical integration simulat...
