Abstract

This paper presents the free vibration analysis of axially loaded rotating functionally graded (FG) cylindrical shells made up of stainless steel and nickel. The properties are graded in the thickness direction according to a volume fraction power-law distribution. Taking account, the effects of centrifugal and Coriolis forces as well as the initial hoop tension, the equations of motion for the rotating FG shell are formulated using Love’s first approximation theory. The frequency characteristics for FG cylinders are investigated using closed form solutions for simply supported cylindrical shell. The effects of length to radius ratio, thickness to radius ratio, material gradient index, and axial load are investigated on the natural frequencies of rotating cylinder.
