| Abstract: | A finite-element formulation is presented for geometric and material nonlinear strength and stability analysis of plate and shell. The triangular plate element based on discrete Kirchhoff assumption is used. The element stiffness matrix and geometric matrix are expressed as explicit function. The program developed is used for computing stress, bifurcation buckling load and limit buckling load. Some numerical results for stress and stability are obtained for plate, shells and cone-cylinder jointed shells. |
