Meso-scale characteristics of particle metal materials (PMM) play an important role in determining its macro-scale mechanical property. In order to investigate relationship between meso-scale characters (particle size, distribution, morphology, porosity) and macro-scale mechanical property, a FEM meso-scale model which can follow the distribution of real structure was built with reasonable simplification. By exploiting AUTODYN FEM software, shock compression process of PMM was simulated and Hugoniot parameters of typical PMM were extracted. Based on the simulated results, conclusion was made on how the meso-scale characteristics (e. g. theoretical mass density, particle size) make impact on the macro-scale shock compression mechanical property. Deformation morphologies and temperature rise during shock compression were also acquired by simulations. It is shown that the simulated result shows a good agreement with the experiment and the meso-scale characteristics of PMM play an important role on its macro-scale property.
