Vibration analysis of rotating laminated cylindrical shells

Free vibration analyses of rotating laminated cylindrical shells are carried out by the ABAQUS (c) finite element program. The fundamental frequencies of rotating laminated cylindrical shells with a given material system are then maximized with respect to fiber orientations by using the golden section method. The significant influences of rotating speed, end conditions, shell thickness, shell length, and shell radius on the maximum fundamental frequencies and the associated optimal fiber orientations are demonstrated.
