This paper presents a crack identification in a rotor dynamic system based on changes in natural frequencies predicted from the transfer matrix approach using a crack point matrix defined in terms of stress intensity factors. A local flexibility of the system due to crack is employed and changes in natural frequencies of the system are illustrated. Effect of cracked and it is location along the length is studied by using some interpolation formula. A generalized transfer matrix approach is applied after validating with the finite element model. Analytical results are compared with those obtained from numerical model through ANSYS. Fatigue analysis of cracked rotor shaft system containing the bearing at ends is performed using solid modeling tool. The results are compared and conclusions are drawn.
