| Abstract: | Nonlinear dynamic buckling of rectangular sandwich plates under in plane harmonic load is analyzed. Based on Reissner's and Hamilton's principle, the governing motion equation for geometrically nonlinearity of the plate is derived. By using Galerkin technique and double parameters perturbation method, the boundary of the principle instability region of simply supported plate is determined. The effects of geometrical and physical parameters on the dynamic stability are discussed. |
