“…The stress level in the region with a crack is another factor established in [9,13] that affects the rate of change in the damping characteristic: a crack located in a weakly stressed region cannot noticeably change the damping characteristic. In addition, experimental studies [18,19] showed that the intensity of changes in the damping characteristic is different for transverse, longitudinal, and torsional vibrations and strongly depends on the coefficient of flexibility.…”
