Static and dynamic crushing of circular aluminium extrusions with aluminium foam filler

An experimental programme consisting of 96 tests was carried out to study the axial deformation behaviour of triggered, circular AA6060 aluminium extrusions filled with aluminium foam under both quasi-static and dynamic loading conditions. The outer diameter and length of the columns were kept constant at 80 mm and 230 mm, respectively. The main parameters in addition to the loading condition were the foam density, the extrusion wall strength and the extrusion wall thickness. Based on the experiments, design formulas for prediction of average force, maximum force and effective crushing distance were suggested.
