Influence of Local Surface Damage on the Natural Frequencies of the Higher Modes of Flexural Vibration of Cantilever Rods

The operating life of gas turbine engines is, by and large, dependent on the reliability of compressor rotor blades that are subjected to a complex set of forces of a different nature during their operation, and in particular, to mechanical damage resulting in severe accidents and material losses. T...
