Summary
  • This report is establishing the multi-phase modelling capability for evaluation of mitigants against blast and fragmentation. The work analyses states of a highly porous material under shock compression. A two-phase model accounting for the inter-phase heat transfer is suggested and employed. Numerical analysis of wave structure in a porous copper is conducted and a simplified method of Hugoniot analysis is developed, which is associated with specification of equilibrium states within the shock transformation. Three types of inter-phase equilibrium within the shock transformation are distinguished. This state classification results in different loci that are seen as Hugoniots when certain thermodynamic parameters are in equilibrium; parts of the loci form a composite Hugoniot curve. Corresponding composite Hugoniots demonstrate a good correlation with available experimental data for porous metals.
