“…Santosa et al (2000), Hanssen et al (2002) and Reyes et al (2004), to name some of the most recent work, used explicit dynamic finite element codes like LS-DYNA and PAM CRASH to perform this kind of simulation. Some key issues in the modeling, such as material model for aluminum foam, contact definition, friction effect, boundary condition and the bridge from dynamic to quasi-static were discussed.…”

The ''interaction effect'' between aluminum foam and metal column that takes place when foam-filled hat sections (top-hats and double-hats) are axially crushed was investigated in this paper. Based on experimental examination, numerical simulation and analytical models, a systemic approach was developed to partition the energy absorption quantitatively into the foam filler component and the hat section component, and the relative contribution of each component to the overall interaction effect was therefore evaluated. Careful observation of the collapse profile found that the crushed foam filler could be further divided into two main energy-dissipation regions: densified region and extremely densified region. The volume reduction and volumetric strain of each region were empirically estimated. An analytical model pertinent to the collapse profile was thereafter proposed to find the more precise relationship between the volume reduction and volumetric strain of the foam filler. Combined the superfolding element model for hat sections with the current model according to the coupled method, each component energy absorption was subsequently derived, and the influence of some controlling factors was discussed. According to the finite element analysis and the theoretical modeling, when filled with foam, energy absorption was found to be increased both in the hat section and the foam filler, whereas the latter contributes predominantly to the interaction effect. The formation of the extremely densified region in the foam filler accounts for this effect.

“…Previous studies show that foam density is one of the key factors that affect the crushing behavior of the aluminum foam and the filled structures. Gibson and Ashby (1997), Hanssen et al (2000c) and Reyes et al (2004) found that aluminum foams obey the powerlaw relationship…”

“…The crush behaviour of mild steel square columns was analysed by Han and Park [15], indicating that from the axial to the bending collapse mode, there was a critical load angle at the transition place. Reyes et al [16][17][18][19] studied square aluminium extrusion response, square tubes with and without foam, and circular tubes subjected to oblique loading, and obtained both experiment and simulation results. In addition, Li et al [20] carried out deformation and energy absorption testing, using the experiment results for aluminium foam circular tubes, subjected to an oblique quasi-static loading.…”

“…Figure 21 shows how the mean crushing force drops as a function of loading angle (θ = 0° refers to pure axial crushing) for tempers T4 and T6. The plastic hinge over the cross section of obliquely loaded members will be subjected to both axial force N and bending moment M. Reyes et al (2004a) plotted the axial force and bending moment occurring in the plastic hinge for the same rotation and obtained interaction curves, see Figure 22 for foam filled T4 and T6 extrusions. Note how the interaction envelopes shrink as the deformation proceeds, reflecting the softening behaviour of the obliquely loading member as given in Figure 18.…”

This paper presents experiences gained at SIMLab in modelling and design of aluminium-foam-filled tubes for structural applications. The main challenges for robust finite element simulations using explicit codes are outlined and references to previous studies are used for illustration. Any details whatsoever may be found in the original papers referenced in the text. Magnus Langseth is Professor of Aluminium Structures at the Norwegian University of Science and Technology. Langseth is the author of more than 60 papers in international journals and more than 70 papers at international conferences. These publications are manly worked out together with the 11 PhD students he has supervised in the period 1990-1999, and the nine PhD students he at present is supervising. Topics for his research have been accidental loads in the offshore industry with special emphasis on dropped objects (topic of his dr. ing. thesis), forming of aluminium components and stability of plated aluminium structures. His present research activities are primarily related to impact and crashworthiness of aluminium, magnesium and high-strength steel structures as well as light-weight ballistic protection. Keywords
