Free vibrations of rotating adhesively bonded orthotropic plates (Q1275812)

Summary: We investigate free vibration analysis of rotating adhesively bonded specially orthotropic plates. A first-order shear-deformation plate theory, including geometric nonlinearities in the form of von Kármán strains and the effects of rotatory inertia and Coriolis forces, is used to predict the free vibration frequencies and mode shapes. In the analytical model, the thin interlaminar adhesive layer is considered as mechanic springs. The non-linear equations of motion and the appropriate boundary conditions are derived by means of a variational method in conjunction with Hamilton's principle.
