摘要: An experimental programme consisting of 144 tests was carried out to study the behaviour of triggered, square 80× 80mm2 AA6060 aluminium extrusions filled with aluminium foam under both quasi-static and dynamic axial loading conditions. The main parameters in addition to the loading condition were the foam density, the extrusion wall strength and the extrusion wall thickness. Previously proposed design formulas applied to these components under static loading were found to be valid, and a simple modification introduced in order to …
