✦ Synopsis

The dynamics of asymmetric rotors has been investigated in the literature. However, considering the importance in the practical "elds, the vibration characteristics of slotted shafts are not studied in detail. It needs more attention particularly with the emerging of new materials, such as composites for shafts. The present study aims at the analysis of the slotted shafts including the compensatory inertia slots. Also, the slotted composite shaft has been modelled based on "rst order shear deformation theory using "nite element method with shell elements. Di!erent materials such as, Boron epoxy, Carbon epoxy and Graphite epoxy have been tried for various stacking sequences. The slot parameters, stacking sequences and material properties have found to in#uence to great extent on the vibrational characteristics of rotors. The results are compared with those of isotropic slotted shaft.

This work presents the governing equations for both the in-plane motion and out-ofplane motion of a curved hollow shaft. Two types of shaft structures, which are a curved hollow shaft and a straight}curved}straight hollow shaft, are considered. An analytical method is also presented to examine the f
