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.<\/jats:p>","DOI":"10.1155\/2013\/620267","type":"journal-article","created":{"date-parts":[[2013,2,4]],"date-time":"2013-02-04T21:05:25Z","timestamp":1360011925000},"page":"1-6","source":"Crossref","is-referenced-by-count":4,"title":["Optimal Variational Method for Truly Nonlinear Oscillators"],"prefix":"10.1155","volume":"2013","author":[{"given":"Vasile","family":"Marinca","sequence":"first","affiliation":[{"name":"Faculty of Mechanical Engineering, \u201cPolitehnica\u201d University of Timi\u015foara, Bd.
