Micromechanical model of nanoparticle compaction and shock waves in metal powders

•Micromechanical model of a metal powder compaction is developed.•Stage of particles, percolation transition and stage of porous medium are incorporated.•Bayesian algorithm and MD data are implemented for parameter identification.•The model is included into a numerical scheme of shock wave propagati...
