A finite element model is applied to the non-conservative stability problems of a cracked thick rotating blade. This finite element model can satisfy all the geometric and natural boundary conditions of a rotating blade. The blade is considered to be subjected to follower moments and aerodynamic forces. The effects of crack locations and crack sizes are studied. It is found that the rotation speed and crack can change the stability characteristics of a non-conservative system.
