Abstract

The loss of stability is critical regarding thin-walled composite structures which are widespread in weight critical applications. For the example of omega-stringer stiffened panels, the buckling and postbuckling behavior is investigated using closed-form analytical approximate solutions. They are derived based on energy methods and their focus lies on local stability behavior. Hereby, different load cases are included and the quality of the computational models is assessed in comparison to Levy solutions or finite element analyses.
