Abstract:

The report develops the solution for a cross stiffened plate with mass leading around the edges subject to in impusive loading. Orthotropic plate theory is used to model the stiffened plate. Two solutions are obtained. The first is based upon mode approximations using products of beam functions with edge mass and inertia to represent the modes. The second solution is a finite difference solution. Computer programs and numerical results are given for the first solution. All the necessary equations are set up for the second solution in order to carry out either a modal analysis or a differential equation analysis of a 25 element cross stiffened plate with variable mass and stiffness properties.
