Abstract

Extensive research is currently being devoted to the mechanical characterisation of aluminium foam. The majority of existing unit-cell-based models assume ideal unit-cells and ignore the existence of microstructural defects, which greatly influence the mechanical behaviour of the foam. Furthermore, it is numerically exhaustive to directly incorporate these defects into single scale finite element models. Therefore, it is the objective of this paper to present a multiscale methodology to enable the modelling of these microstructural features at the global scale.
