Abstract

The presented approach combining nonlinear global arid linear local investigations represents an analysis concept for stiffened composite structures, which considers the stability behavior of the structure as well as ply failure and onset of delamination in the skin, the stringers and the skin-stringer transitions. Special emphasis is focused at discussing a local generalized plane strain model in combination with a specific procedure for determining the boundary conditions which allow local analyses to be linear although the global analysis might be geometrically nonlinear. Comparisons with results obtained from a full 3D-solid shell finite element analysis prove the applicability of this approach. Finally, an application to a flight hardware component is demonstrated.
