This paper presents experiences gained at SIMLab in modelling and design of aluminium-foam-filled tubes for structural applications. A general summary of existing work on generic foam-based components for crashworthiness applications have been given. Where available, design formulas have been added. Several of the experimental results presented have been the basis for comparison with finite element simulations. It appears that foam-filled structures pose a considerable challenge when it comes to finite element modelling as the foam filler will directly influence the behavior of the surrounding material. Here, the paper has demonstrated by several examples that failure of aluminium foam in parts subjected to tensile stresses must be captured in order to predict the overall response of the structure well. Any details whatsoever may be found in the original papers referenced in the text.
