These vibration modes are called the split modes, and those associated with the repeated natural frequencies are called the repeated modes.
A relationship identifying the split and repeated modes for any configuration of slots is presented.
The results obtained are ultimately extended to the case when the system has some repeated modes, none of which is a DFM.
Two different case studies involving a plate with closely spaced modes and a pulley ring with greater extent of closeness in repeated modes are presented.
Parametric instability can be excited in the split modes of the plate by the springs rotating below critical speed, but it cannot be excited in the repeated modes.

The theoretical predictions of split and repeated vibration modes and of the excitation of parametric instability are confirmed by experiments.
Finally, the vibration of circular plates with evenly spaced radial inclusions, which cause splitting of some of the repeated vibration modes, is analyzed both analytically and numerically for the eigensolutions.
