Abstract:Â In this paper, the present work deals with modal analysis of uncrack and crack cantilever beam using FEA. Faulty structure subjected to change in local flexibility which affects vibration response of the structure. Therefore it is necessary to study the effect of fault on the structure. In this paper, aluminum un-crack and crack cantilever beam is used for analysis. Un-crack beam and cracked beam analyzed by using Euler equation considering various crack positions for the beam. Modal analysis of un-crack and crack beam is performed to find deflection and natural frequencies of beam. The results are presented in tabular form to show the effect of crack on change in natural frequencies. ANSYS software was used for the analysis of un-crack and crack beam.
