| Popis: | A two-phase analysis is very restrictive in the case when the gaseous phase of a two-phase material is of critical importance for description of the shock response of porous reactive and energetic materials because condensed constituents are often heterogeneous. A three-phase constitutive model is considered, where a three-phase material is described as a whole with a unified set of conservation laws and behaviour of individual phases is described with a set of constitutive equations responsible for the inter-phase exchange of physical quantities. The present work introduces a description of the gaseous phase in the model, which enables one to simulate behaviour of porous materials with two condensed constituents. The present analysis employing the model for graphite-metallic porous mixtures shows a good description of Hugoniot experiments available in literature. |
