FIG. 1.

(a) Foam specimen as prepared for dynamic compression. (b) Foam specimen after dynamic compression showing several densified pieces among other crushed pieces. [(c) and (d)] Electron micrographs of a densified piece of a dynamically compressed foam.

FIG. 2.

Dynamic stress-strain response of foams of varying relative density (reported in % porosity) for strain rates of 3000.

Image of FIG. 3.
FIG. 3.

A comparison of the stress-strain response of two 60% porosity foams under applied strain rates of 3500 and .

Image of FIG. 4.
FIG. 4.

Relative strength plotted against relative density for foams tested under low and high applied strain rates. The inset shows a data for quasistatic and dynamic compression of aluminum foams (Ref. 19). Solid lines are power-law fits to the data.
