Optimal Variational Method for Truly Nonlinear Oscillators

Abstract EN

The Optimal Variational Method (OVM) is introduced and applied for calculating approximate periodic solutions of “truly nonlinear oscillators”.

The main advantage of this procedure consists in that it provides a convenient way to control the convergence of approximate solutions in a very rigorous way and allows adjustment of convergence regions where necessary.

This approach does not depend upon any small or large parameters.

A very good agreement was found between approximate and numerical solution, which proves that OVM is very efficient and accurate.
