Abstract

The phenomenon of delamination is common in composite beams as the composite beams are having laminate structures. Delamination leads to development of cracks and reduces the strength of the material. This paper deals to analyze the effect of vibration on the delaminated beam. A FEM model is constructed using Euler Bournouli beam theory. Basically the model is consisting of a single symmetric delamination at the centre of the beam. The beam is considered as group of beam and each beam satisfies the boundary and continuity conditions at the points of joining and at ends. This model gives the idea about the natural frequency of vibration of beam without subjecting the beam to actual conditions. Furthermore, the model can be modified according to the length and the position of delaminated surface.
In this project the modeling is done by finite element method using matlab as mathematical software tool.
