dcterms:description
In this paper an evaluation of microstructural finite element (micro-FE) models of closed-cell aluminium metal foam is given. A comparison of results for models generated on the basis of two different discretization schemes defined for open-cell and closed-cell materials is presented. Discretization is based on regular network of elementary cells having cubic form as defined by Gibson et al. Results are studied with respect to characteristics of the reference Alporas aluminium closed-cell foam. An open-cell discretization scheme is here considered intentionally to evaluate its capability to describe deformation mechanisms and to estimate the compressive elastic modulus of the reference material. The influence of geometrical parameters of the elementary cells is assessed prior to determination of the dependence of the elastic modulus on material porosity.
