ABSTRACT
In this article, we present a proposition of a model of the compressive behaviour of open-
-cell aluminium with relation to the material apparent density. The research was based on
experimental data from uniaxial compression tests conducted for two sample lots. These
results were analysed with the use of neural networks in a specially designed algorithm.
The main criterion for choosing a satisfactory approximation was mean absolute relative
error MARE<5%. As a result of the analysis, the sought relation was extracted and is
presented as a proposition of a new ANN model of the compressive stress-strain relationship
for aluminium sponge.
