Verification of Vibration of Composite Beam with Crack by using Finite Element Method and Experimental Method

Abstract

This paper presents evaluation of analytical and experimental result discussion for vibration analysis of composite beam with crack. Beams and beam like elements are principal constituents of many mechanical structures and used widely in high speed machinery, aircraft and light weight structures. Finite Element Analysis is carried out using ANSYS 14.5. The model of beam is prepared and used for Finite Element Analysis. The model analysis is used to determine the natural frequencies and mode shapes of a structure. The experimental analysis is conducted by using a Fast Fourier Transform (FFT) device which is used to detect the potential faults and checking the status of the machine through the vibration analysis.
