| Abstract: | This paper presents the method that highlights the damage pseudo-severity that exists in the damaged beam for a specific position of the damage by using the relative frequency shift obtained from natural frequencies values and compares it with the square of the second derivative of the vibration mode shape from the analytical calculation. The natural frequencies are obtained from the numerical method for a healthy and damaged beam. For three damage depth, the damage is considered at the clamped end and at a specific position. Finally, the results confirm that for each vibration mode, regardless of the depth of the damage, the severity is the same. |
