"WebBackground. High cycle fatigue failure in turbomachinery is known to be attributed to two major factors, flutter and forced response. Flutter is caused by the blade vibration, which results in negative aerodynamic damping. This research proposes an effort to investigate computationally the forced response behaviour of a 3.5 stage compressor. " - Flutter aeroelasticity
