      Results of numerical simulations for spall fracture of natural uranium under high-rate deformation in expansion counter-waves. Spall fracture process is described using kinetic micromechanical model with internal parameters treating the fracturing as continuous emergence and increase of defects followed by coupling find macrofissure formation.
      Specific parameters values for kinetic model are given. The comparison with experimental data shows that computational results agree with principal laws of spall fracturing for metals.
