[en] A series of elastoplastic large-deflection finite element analyses is performed on stiffened aluminium plates with flat-bar
stiffeners under in-plane longitudinal compression loads. Then, the closed-form ultimate compressive strength formula is
derived for stiffened aluminium plates by regression analysis. Finally, artificial neural network methodology is applied to
predict the ultimate strength of uniaxially compressed stiffened aluminium plates. It is found that artificial neural network
models can produce a more accurate prediction of the ultimate strength of the stiffened aluminium plates than can the
existing empirical formula.
