Analysis of flexural-torsional buckling of rectangular beams via Ritz and power series methods

Abstract

In this article, flexural-torsional buckling analysis of a beam is conducted using both power series and Ritz methods. Even in the linear stability analysis, extracting a characteristic value from an exact solution for some cases is not an easy task. However, by the use of presented approaches this difficulty can be overcome easily. This issue is presented with case studies and the results show that presented techniques can be used successfully in the analysis of flexural-torsional buckling of beams.
