The whirl speeds and unbalance response of a cantilever shaft-disk system with a localized region of damage are studied by the finite element technique. The effects of translational and rotatory inertia, gyroscopic moments, bending and shear deformation have been taken into account. Four parameters are employed to describe the total effect of the damaged zone, including location, size, effective bending and shear stiffness. Numerical results show that the presence of damage can reduce whirl speeds.
