We describe the results of our experimental investigations aimed at the analysis of the influence of the parameters of defects in the form of open edge cracks (depth and location) on the formation of the spectrum of eigenfrequencies and the level of vibration stresses in similar elements of a regular system. It is shown that our results are in good agreement with the results of computations.
