Abstract
The periodic response of a one-degree of freedom system with cubic nonlinearities to a principal resonance is investigated. The modified homotopy perturbation method is used in order to determine the equations that describe the second-order approximate periodic solutions of the system. Results obtained are compared with the numerical integration results and a good agreement is found.
