The theory accounts for geometric non-linearity in the form of von Karman strains. The plate is permitted to have arbitrary orientation and offset from the axis of rotation. A finite element model is developed to obtain a solution to the problem. The model is validated by comparing the results for free vibration of non-rotating plates for various boundary conditions and material properties with the exact results based on the classical plate theory and the first-order shear deformable plate theory. Results are presented for free vibration of isotropic and laminated composite plates rotating at different angular velocities. A study has also been made on the change in the free vibration frequencies of the plate with angular velocity for different plate thicknesses and for different modulus ratios.viii, 116 leavesBTDapplication/pdfenIn CopyrightLD5655.V855 1989.B485Finite element methodPlates (Engineering) -- VibrationThesishttp://scholar.lib.vt.edu/theses/available/etd-06122010-020632/
