The process of formation of the energy field by the explosion of a conical charge has been mathematically simulated. The features of the development of the energy field, depending on the point of initiation of the truncated cone explosive charge, were determined. The complex nature of the use of a charge at the bottom of a borehole with an intermediate conically-shaped detonator is discussed. Possible technological directions for using a charge with a complex shape are proposed.

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.

The results of modeling the operation of shaped charges with conical, biconical, and elliptical liners and various detonation initiation schemes are presented. A comparison of the modeling results with data from experimental studies conducted on charge models and with the results of modeling by other authors has been carried out. A dependence of the leading part velocity of the copper shaped-charge jet for copper liners with apex angles of 44-50° on the parameter ρD2 in the low detonation velocity (D) and explosive density (ρ) range, is proposed.
