| Abstract: | This paper presents a solution of the nonlinear dynamic buckling of stiffened plates under fluid-solid impact loading. Based on the larger deflection theory and the discretely stiffened plate model, the tangential stresses of the stiffeners and in-plane displacement are neglected, and then applied to the Hamilton's principle, the motion equations of stiffened plates are obtained at last. The deflection of the plate is taken as Fourier series, and the discretely equations can be got by the Galerkin method, which can be solved easily by runge-kutta method. The dynamic buckling loadings of the stiffened plates are obtained based the B-R criterion. |
