- Summary:
-
The report studies the constitutive behaviour of highly porous materials. This study is driven by efforts for the development and validation of a multi-phase modelling capability in DSTO, which aims at an enhanced evaluation of blast mitigation by porous materials. A two-phase model is employed for the description of a porous material, for which experimental shock velocity data are widely available in literature. The method deriving Hugoniots from the shock velocity data is critically approached. The importance of the non-equilibrium behaviour analysis is demonstrated, and it is shown that the stress or velocity profiles need to be considered, using relevant experiments and constitutive modelling. It is argued that the apparent anomalous behaviour of the Hugoniots of a highly porous material might be caused by misinterpretation of the experimental data.
