A rotating disc often undergoes severe vibrations at high speeds because of unstable joining between the disc and the drive shaft. The analysis has presented the effect of shear Stress with different profiles of the flywheel with different layered (0.5mm, 1mm) and different Hub angle (4˚, 5˚, 0˚). The natural frequency and modes of different materials and shear stress effects were analyzed on different profile and materials of flywheel and distribution along the flywheel was studied. The natural frequency along the flywheel profile is found to be maximum of the 4˚hub angle of T300 material profile with 1mm multi rim flywheel. The shear stress distribution along the multi rim flywheel is maximum for T300-EPOXY non layer and minimum for T300-EPOXY 1mm layered of a flywheel with different profiles. The magnitude of frequency is maximum in the case of T300 material profile with 4˚ hub angle. The nature of the natural frequency is maximum near its end in 1st 2nd and 3rd mode. The nature of the shear stress is minimum near its hub of flywheel with 1mm multi rim of T300-EPOXY and 4˚ inclined hub angle.
