✦ Synopsis
A computationally ecient numerical technique is developed for determining the natural frequency and mode shapes of uniform beams with a transverse edge crack. The ¯exibility due to crack presence is determined using fracture mechanics principles. The results of the frequency analysis for cantilever beams were compared with experiments conducted to verify the theory, as well as experimental, numerical and ®nite element results reported in the literature. The comparisons show that the method is a useful means of predicting transverse vibration of cracked beams. The results of the analysis show that the eect of crack location on beam vibration is rather complex.
