Vibration Analysis of a Laminated Composite Beam with Non-ideal Boundary Conditions

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
