Abstract
Geometry size has a great influence on energy absorption ability of
closed-cell foam metals. Study on energy absorption ability of closed-cell Si-Al
foam metals considering geometry size by impact experiment method. The results
show that the strain and absorbing energy value are decreasing with the geometry
size increasing, and also lead to the hole wall rupture or whole instability. The best
height-width ratio for cube and cylinder are 1.0–1.5 and 1.0–2.0, respectively. With
the increasing of material diameter, the compressive strength increasing quickly,
but the strain reduces. It is clearly that height-width ratio 1.0 is better for cube and
cylinder.
