Abstract
In a design and test project aimed at investigating the compressive buckling
strength of welded aluminium alloy fuselage panels, analyses were performed
using conventional stressing methods incorporating modifications to allow for the
loss of strength which occurs in the heat-affected-zone (HAZ) which surrounds a
weld made in this material. Due to inherent conservatism and necessary
simplifications, it was not possible to determine if the modified analysis methods
were valid or accurate. In light of this, simple FE analysis methods were also
used to predict the strength and behaviour of the test specimens used in the
project and, thus, to determine if FE methods offer the potential for more accurate
analysis of this type of structure or even the potential as a first cut desi
