Generic Linking of Finite Element Models for non-linear static and global dynamic analyses of aircraft structures

Depending on the type of analysis, Finite Element(FE) models of different fidelity are necessary. Creating these models manually is a labor intensive task. This paper discusses a generic approach for generating FE models of different fidelity from a single reference FE model. These different fidelity models are created by sub-structuring and a multi-scale superposition technique. Efficiency of the developed approach is demonstrated via non-linear static and modal analysis of a carbon-fiber stiffened panel.
