Abstract
The prediction of the behaviour and the ultimate load for compressively
stiffened aircraft shell structures is a very important non-linear analysis
problem for engineers. Herein, finite element analysis and experimental tests
are carried out for the buckling of aircraft stiffened fuselage panels. The
calculated finite element results for both flat and curved bulbed-T panels
correlated well with the experimental results. A change of mode shape is
observed for the curve panel, which is very imperfection sensitive. This study
reveals that the finite element code used, ABAQUS is capable of modelling
the behaviour of the buckling phenomenon for small aircraft fuselage panels.
