Podgorny's Institute of Mechanical Engeneering Problems of the National Academy of Science of Ukraine popup.description2 This work studies multivariate numerical results of the oscillations of blades with a different number of cuts, which are located in different places along the length of the blade. The peculiarities of the distribution of stresses in damage zones for both individual blades and working wheel have been revealed. It is shown that an increase in the number of cuts leads to an increase in the zone of increased stress, but does not cause a greater stress concentration. The value of the stress concentration and the fatigue limit of the blade material in the damage zone were revealed. Recommendations for the prevention of dangerous vibrational stresses during the operation of blades in a wet steam environment have been developed.
