چکیده:

This paper deals with the vibration analysis of an Euler Bernouli laminated composite beam subjected to axial loading. The end condition of the beam has clearance which is considered as a non-ideal end condition. The governing equation of the system is derived as a homogenous partial differential equation. The perturbation parameter ε is used to model the non-ideal boundary conditions. The problem is solved by Lindstedt – Poincare technique and the effects of the clearance on the amplitude and frequency of the vibrations as well as the critical buckling load, arestudied and discussed
