Constraint method analysis of stiffened plates

The constraint method is applied to the finite element static analysis of concentrically and eccentrically stiffened plates. The displacement fields in the stiffener are expressed in terms of the displacements of the middle surface of the plate. Superposing the strain energy of plate and stiffener, the stiffness matrix of the compound structure is obtained, for arbitrary order of approximating polynomials. Several example problems are analyzed.
