Abstract
It was reported recently that closed cell A1 foams exhibit strain hardening when subjected to monotonic or cyclic loading with lateral constraint. In the present study compressive and fatigue testing was carried out on some A1poras foams with lateral constraint. The deformation mechanisms responsible for this behaviour were examined in this study, by employing non-destructive X-ray tomography on load-interrupted specimens. Foam deformation mechanisms with constraint, studied from the tomograms, were compared with the literature data on foam deformation mechanisms without any constraint. It was found that the deformation mechanisms are similar in both cases.
