摘要：

In the range of weak shock waves (before absorption of elastic precursors by the shock wave), the effects of shock wave deformation of aluminum and beryllium alloys are numerically studied by a relaxation model with the dislocation kinetics of plastic shears. The structures of non-stationary and stationary shock wave profiles are modeled. The plastic flow behind the elastic precursor front is studied.
