Asymptotic Solutions of Fourth Order Near Critically Damped Nonlinear Systems

Md. Habibur Rahman, B.M. Ikramul Haque, M. Ali Akbar


A perturbation technique is developed in this article to solve asymptotic solutions of fourth order near critically damped nonlinear systems based on the Krylov-Bogoliubov-Mitroplskii method. The method is illustrated by an example. The results obtained by the presented technique show excellent coincidence with those obtained by numerical method.
