Abstract
A foam-filled section can be used for the energy absorbing structures. In case of side collision where bending is involved in the crushing mechanism, the foam filler would be effective in maintaining progressive crushing of the thin-walled structures so that more impact energy can be absorbed. In this paper, we produced aluminum alloy foams with various densities using the powder metallurgical method and filled the hollow structures with piecewise foams. Three point bending tests and finite element (FE) analysis were performed to evaluate bending behavior of foam filled cylindrical structures. Obtained results showed that the aluminum alloy foam filling offered remarkable increase of bending resistance and enhanced the crashworthiness of the structure. It turned out to prevent the inward fold formation at the compression flange, and result in the multiple propagating folds and the increase of load carrying capacity. The results simulated by FE analysis were in good agreement with those from experiment.
