Keywords: non-linear modelling, post buckling stiffness, fuselage barrel analysis

This paper reports on the development of a non-linear model for the buckling analysis of fuselage panels. The aim is to increase the accuracy of the global Finite Element model, accounting for variations in stiffness, as behaviour for some components becomes non-linear.
