CHARACTERIZATION OF FIBER-REINFORCED STIFFENER PROFILES FOR AIRCRAFT FUSELAGE PRELIMINARY STRUCTURAL DESIGN

This paper presents a characterization module for stiffener profiles. It is part of a modeling and analysis tool for stiffened structures in aircraft fuselage design. The module offers options to determine mechanical characteristics of a given section such as mass, stiffness, and failure loads for strength and local stability. For the characterization, analytical approaches and the Finite Element Method (FEM) are used. Both ways are presented and the results are compared as part of the verification of the module. Furthermore, how the module can be used for a basic comparison of design concepts is described.
