Analytical accurate solutions of nonlinear oscillator systems via coupled homotopy-variational approach

In this paper, the coupled homotopy-variational approach (CHVA) based on combining homotopy with the variational approach is applied to solve the nonlinear Duffing equation, and new frequency- amplitude relationships are obtained. The coupled method works very well for the entire range of initial am...
