Abstract
AbstractThe imperfection sensitivity of stiffened cylinders is analysed on the basis of a critical perturbation associated with a minimum of strain energy. To identify worst perturbations including displacements and stresses, the perturbation energy concept is used, which is developed for mixed finite elements. Disadvantages in modelling branched structures due to stress discontinuities are avoided by transferring the concept to a mixed‐hybrid formulation. Beside an evaluation of common design recommendations, the identification of non‐initial perturbations lead to an insight into the quite complex buckling behaviour of stiffened shells.
