Why is it important?
Breathing crack is a practical form of early cracks and results in nonlinear vibration response. While tenon connection and shroud contact are common structures in aeroengine rotated blades, which can also lead blades to vibrate nonlinearly and seriously interfere online identification of early cracks.
