The objective of this paper is to update its readers the various vibration based Crack diagnosis techniques presented by various researchers for a crack ed structures. These methods use "theoretical finite element analysis techniques, together with experimental results, to detect damage in different types of beam like cantilever, fixed - fixed beam, simply supported beam. Damage in structure alters its dynam ic characteristics. It results in reduction of natural frequencies and changes in mode shapes, stiffness of the beam. An analysis of these changes makes it possible to determine the position and depth of cracks.
