The presence of cracks serves as a threat to the performance of structures and it affects the vibration signatures (Natural frequencies and mode shapes). The presence of crack in a structural member causes change in stiffness of that structure. The objective of this work is to evaluate the effect of crack location and crack depth on natural frequency of clampedclamped composite beam of Glass Epoxy. Here transverse crack is created on the beam at 110 mm, 220 mm and 330 mm from fixed end, the

A higher order 3-D shell element, SOLSH190 element is used in analysis. The result of the study concludes that, presence of crack changes the natural frequencies and the mode shape of vibration.
