The goal of this thesis is to investigate the dynamic and static compaction characteristics of porous silica powder. This goal is accomplished by experimentally evaluating and comparing the static compaction characteristics, and numerically evaluating and comparing a variety of equations of state governing dynamic compaction of porous materials. The static results showed that the silica powder has an internal porosity that is unaffected by the static compaction process of making a porous silica wafer. The dynamic results show that the previously unverified KO for the relatively low shock velocity - particle velocity region and highly distended powders predicted the experimental results as well as CTH. Neither the P-acompaction model nor the MieGriineisen model was able to accurately predict the dynamic compaction characteristics of porous silica powder.
