Abstract: During the last few decades, intense research on the detection of crack using the vibration based techniques has been done and various approaches have been developed by researchers. In the present paper, detection of the crack presence on the surface of composite cantilever beam -type structural element using natural frequency is presented. First three natural frequencies of the cracked beam have been obtained experimentally and used for detection of crack location and size. Detected crack locations and size are compared with the actual results and found to be in good agreement. Also, the effect of the crack location and the crack depth on the natural frequency is presented. Experimental Modal Analysis (EMA) was performed on beams with cracks and the measuring first three natural frequencies changes. To identify the crack, contour of each normalized frequency in terms of the normalized crack depth and location are plotted. The point of intersection of three curves gives crack location & depth. It is observed that, results obtained from experimental method have a very good agreement with actual results also we can justify the results through simulation.
