چکیده مقاله

In this paper, generalized differential quadrature method (GDQM) is employed to analyze vibration of a rotating disks by considering effect of radial and circumferential in-plane stresses. Natural frequencies and vibration modes are derived numerically. First, the versatility and accuracy of the presented solution are tested against presented exact results. Then, effects of the ratio of radii, rotation speed and circumferential mode number on the natural frequencies are investigated.
