Large deformation solution of stiffened plates by a mixed finite element method
A finite element mixed variational functional and the iterative equations of the eccentrical orthogonal stiffened plates are developed in accordance with nonlinear elasticity. The nonlinear equations are transformed into instantaneous linear equations; and by using the conjugate gradient method the linear equations are solved.
