Using the finite element model of the shock system, the efficiency of the shock pulse energy transfer to the deformation zone under wave strain hardening is studied. It was established, that conducting research from the point of view of the efficiency of transferring the shock pulse energy to the deformation zone, and from the point of view of the design of the shock pulse generator, is advisable on shock systems in which the contacting ends of the striker and the waveguide have equal diameters. Studies showed that with ratios 1<L1/L2<10; 5<L1/d1<10, an increase in the fraction of the shock pulse energy transmitted to the deformation zone n exceeds 80% for the striker and waveguide with diameters of 30, 48, 60, 90 mm. According to the adopted optimization criteria, the geometrical dimensions of the striker and the waveguide are determined, which ensure the transfer of the largest amount of shock pulse energy to the deformation zone.
