In this work, based on the Thomas-Fermi statistical model, we modified the calculation method of the Wu-Jing parameters R and investigated the effect of the electronic thermal motion on such parameters as the particle number, the internal energy, and the pressure, inside the metallic crystal structure so as to truly describe the shock compression properties of porous metal materials. A new equation of state was developed for porous materials in which the contribution of the electronic phases was considered explicitly under the condition of different porosity. The relationship between pressure and particle velocity, shock wave velocity and particle velocity was obtained for typical MESMs, for instance different components of W/Cu alloy (dense) and different dense degrees of Al/Ni alloy. Compared with existing models, the equation of state established in this paper is better fitted with the experimental results. The results show that this model can be used to predict the shock compression properties of metal materials under unreacted conditions. The us-up relationship of porous materials does not exhibit an approximate linear relationship as solid materials, due to the shock compression characteristics that are divided into two distinct phases before and after compaction. The shock compression characteristics of multi-functional energetic structure materials are obviously affected by the porosity and material ratio.
