| Abstract: | The results of experimental investigation of the relationship between the natural frequency of the first mode bending and
longitudinal vibrations of titanium alloy and alloyed steel cantilever beams and the crack parameters (crack depth and location)
are presented together with the data on calculation of the relative change of the vibration frequency of cracked beams, which
are obtained by the proposed analytical approaches. Based on a comparative analysis, we choose fairly simple and sufficiently
accurate formulas for calculating the frequencies of bending and longitudinal vibrations of a cantilever beam with an open
or closing crack.
