초록
Vibration analysis of rotating blade is the main purpose of present study. In this work, general formulation is proposed to analyze rotating shell type structures including the centrifugal force, Coriolis acceleration and initial twist. Futhermore, simplified equations are derived for the case of an open circular cylindrical shell. Based on the concept of degenerated shell element with the Reissner-Mindlin's assumptions, the finite element method is adopted for solving the governing equations. (onitted)
