Computationally efficient approximate buckling and postbuckling analysis of prismatic composite structures.
Konferenzveröffentlichung, Bibliographie
Kurzbeschreibung (Abstract)
In order to optimize the design of structures of aircraft and space vehicles in preliminary stages, highly computationally efficient analysis methods are needed. Therefore, a closed-form approximate model is proposed that describes the stability behavior of prismatic composite structures. An example for such a structural element is an omegastringer-stiffened panel that is currently used in the design of aircraft fuselages. The closed-form analysis is achieved by energy methods and aims to describe the stability behavior in the region of the bifurcation point approximately. The loadcase is limited to uniaxial compression. The results are compared to numerical methods. The introduced computational model offers the opportunity to fully utilize the potential of optimization by a highly efficient approximate analysis method.
