Abstract

Computational modelling has been performed to understand the deformation mechanisms of closed-cell aluminium foams under quasi-static compression. A micro-computed tomography-based 3D foam geometry was developed that described the interior of the foam. The FE software ABAQUS/Explicit has been used for the present meso-scale modelling. A good correlation of load-strain response was found between the simulations and experimental results. A sectional view was observed during deformation to explore the internal deformation mechanisms. It was revealed that localized cell collapse occurs due to complex movements of the cell-walls with thin/weaker cells being deformed faster than thick/stronger cells.
