Shock compression of low-density silica aerogels reveals a rate process associated with the crushing dynamics of the aerogel structure. Embedded magnetic impulse velocity gauge (MIV) experiments have been accomplished on density 0.3 and 0.12 g/cm{sup 3} materials. The crushing rate has been determined for the low pressure ({approximately}0.1 to 0.2 GPa) regime, and equation of state (EOS) data have been required. The crushing rate increases with applied pressure in this low pressure region. 7 refs., 4 figs., 2 tabs.
