Free Vibration of Rotating Functionally Graded Material Cylindrical Shells with Orthogonal Stiffeners

Tran Minh Tu, Nguyen Van Loi


In this paper, free vibration analysis of rotating functionally graded cylindrical shells with orthogonal stiffeners is presented. Based on Love’s first approximation theory, using energy approach, the governing equations of motion which take into account the effects of initial hoop tension and also the centrifugal and Coriolis forces due to rotation are derived. To validate the present analysis, comparisons are made with those available in the literature for particular cases; very good agreements are achieved. The influence of the power law index and rotating speed on the natural fundamental frequency of the simply supported rotating stiffened functionally graded shell are investigated.
