TO STUDY THE EFFECT OF CRACK ON NATURAL FREQUENCY IN A CANTILEVER STRUCTURE BY USING EULER'S BEAM THEORY.

The presence of cracks causes changes in the physi cal properties of a structure which introduces flexibility,and thus reducing the stiffness of the structure with an inherent reduction in modal natu ral frequencies. Consequently it leads to the change in the dynamic response of the beam. In this paper,A model for free vibration analysis of a beam with an open edge crack has been presented. Variations of natural frequencies due to crack at various locatio ns and with varying crack depths have been studied. A parametric study has been carried out. The cracked beams with different boundary conditions have been analyzed. The results obtained by Euler�s beam theo ry. https://www.ijiert.org/paper-details?paper_id=14068
