The results of modelling the functioning of shaped charges with different liners and different detonation excitation schemes are presented. The simulation results are compared with experimental data and modelling results by other authors. The shaped charge explosion process was simulated with the help of the authors’ program “Hephaestus” and the ANSYS/AUTODYN program. The results of determining the depth of penetration of cumulative jets into a barrier using the AV model (Allison and Vitali) are compared with experimental data. The dependence of the velocity of the leading part of the copper cumulative jet on the angle at the top of the conical liner is proposed. Attention was paid to the need to take into account the gradient of the properties of the liner material in the simulations.
