DYNAMIC RESPONSE OF AXIALLY LOADED EULER-BERNOULLI BEAMS

The current research deals with application of a new analytical technique called Energy Balance Method (EBM) for a nonlinear problem. Energy Balance Method is used to obtain the analytical solution for nonlinear vibra tion behavior of Euler-Bernoulli beams subjected to axial loads. Analytical expressions for geometrically nonlinear vibration of beams are provided. The effect of vibration amplitude on the nonlinear frequency is discussed. Com parison between Energy Balance Method results and those available in literature demonstrates the accuracy of this method. In Energy Balance Method contrary to the con ventional methods, only one iteration leads to high accu racy of the solutions which are valid for a wide range of vibration amplitudes. http://dx.doi.org/10.5755/j01.mech.17.2.335
