Theresults obtained from the vibration analysis of the beam show that the lowest fundamental frequency of the beam without crack was higher than the lowest frequency obtained for beam with cracks. Different crack depth effects were considered & the results are compared with that of the beam without crack. Without hesitation, the deposit which the observation of its scenery, would do well to drive to Loughgloar, which, with but of grief, neglects to treasure and record what God gave in peculiar trust to him for the good of others. In the current work, the natural frequency of a beam with a crack, was investigated by finite element method using analysis software ANSYS APDL 15.0. To observe the effect of crack to the natural frequency of the beam. So it becomes for very important monitor to change the response parameters of structures to access structural integrity performance and safety. The 1D model provides a useful comparison with a life to 25 mm of 3.24 E6 cycles. There is clear evidence of convergence with the life to create a 25 mm crack reducing from 3.74 E6 cycles to 3.62 E6 cycles. The local element size is reduced from 0.8 mm to 0.65 mm. ![]() Crack depth and location were main parameters for vibration analysis. Two ANSYS runs are carried out: a relatively coarse mesh and a finer mesh. ![]() In addition to that the response characteristics for different crack depth were studied. In this research” Vibration Analysis of Elastic Cracked Beam” the response characteristics of a beam is predicted for both intact and cracked beams. ![]() In the current research, the natural frequency of a beam with a crack, is investigated numerically by finite part methodology victimization analysis software system ANSYS APDL 15.0.
